Tab groups
A tab group keeps related tabs together under a name and a color. Collapse a group to hide its tabs until you need them, or close the whole group at once. Groups work in the tab strip and in the sidebar.
Make a group
- Right-click a tab and choose Move to tab group.
- Choose New tab group. Acira makes a group named New group (or New group 2, and so on if the name is taken) with the tab inside, and opens the editor.
- Type a name and pick a color. Press Enter to save the name.
To add more tabs, right-click another tab and choose Move to tab group, then the group. You can also drag a tab onto the group's header or between its tabs.
What a group looks like
- In the tab strip, a group has a header with its color and name, followed by its tabs.
- In the sidebar, a group has a header with a small folder in the group's color, then the group's name. The folder holds one sheet for each tab in the group, up to three, so a group of one tab shows one sheet and a group of five shows three. The folder closes when the group is collapsed and opens when it is expanded, and a sheet slides in or out when a tab joins or leaves. A small arrow shows when you point at the header, and always while the group is collapsed. Its tabs sit a step in beside a rail in the group's color. A screen reader reads the group's name and how many tabs it has.
A group's tabs always sit together in one block. In the sidebar you can also keep all your groups in an area of their own, above or below your other tabs. See Where groups sit in the sidebar.
Where groups sit in the sidebar
With tabs in a sidebar, open Settings › Tabs › Sidebar › Tab groups to choose where groups sit in the list.
| Choice | What you see |
|---|---|
| With your tabs (default) | A group sits among your tabs, where its first tab is, in the order the tabs were opened. |
| In their own area, above | Every group comes first, then a thin line, then your other tabs. |
| In their own area, below | Your other tabs come first, then a thin line, then every group. |
The line shows only when there are both groups and other tabs. Groups keep their order among themselves. A split view whose tab is in a group stays in that group. Pinned tabs and Favorites keep their own places. Each profile keeps its own choice, and a private window forgets it when it closes. The choice changes only the sidebar list, not the tab strip along the top. Reset sidebar layout puts it back to With your tabs.
Collapse and expand
- Click the group's header to collapse it or to expand it.
- Or right-click the header and choose Collapse group or Expand group.
A collapsed group hides its tabs. In the tab strip, if you collapse the group you are in, Acira moves you to the next tab outside it, or opens a new tab if there is none. In the sidebar, the tab you are on stays visible under the collapsed header. Switching tabs with Ctrl+Tab skips tabs in collapsed groups.
A group folds or unfolds as soon as you click its header. In the sidebar the folder closes or opens with a short animation. It is quicker with Animation speed set to Fast, and there is none with None or Reduce motion. The one case that takes a moment is collapsing the group you are in, in the tab strip, because Acira first picks the tab to move you to.
With a group header focused in the sidebar, Enter or Space folds or unfolds it, F2 renames it, and the Menu key or Shift+F10 opens its menu.
The group menu
Right-click a group's header for these items.
| Item | What it does |
|---|---|
| Edit {name} | Opens the editor with a Group name field and a Group color row. Pick No color, Gray, Blue, Red, Yellow, Green, Pink, Purple, Cyan or Orange. |
| New tab in group | Opens a new tab at the end of the group. A collapsed group opens first. In the sidebar the same thing is the + button that shows at the right end of the header when you point at it. |
| Copy links | Copies the address of every tab in the group, one per line |
| Put group to sleep | Puts the group's tabs to sleep, except any that cannot sleep right now. Shown when at least one tab can. See Tab sleep. |
| Move to workspace | Lists your other workspaces. The whole group goes to the one you choose, with its name, color and tabs. Shown when you have another workspace. Acira says Moved {group} (3 tabs) to {name} and offers Undo. See Move tabs and groups between workspaces. |
| Rename | Edits the name in place |
| Collapse group or Expand group | Hides or shows the tabs |
| Ungroup tabs | Removes the group and keeps all its tabs |
| Close group… | Asks, then closes every tab in the group with Close N tabs. Choose Cancel to keep them. Acira says Group "{name}" closed and offers Undo. |
To rename in the sidebar you can also double-click the group's name.
When every tab of a group is asleep, the group looks dimmer: its name and count in the tab strip, and its name and folder icon in the sidebar.
Take a tab out of a group
Right-click the tab and choose Remove from group. The tab keeps its place. To put it in a different group, choose Move to tab group and a group name.
Rules and limits
- A group name is 1 to 64 characters. Names must be different within a profile and workspace. If you type a name that is taken or leave it empty, Acira says Choose a unique, nonempty name. A group with the same name can exist in another workspace, because groups belong to a workspace.
- Pinned tabs cannot be in a group. Pinning a tab removes it from its group. Putting a pinned tab in a group unpins it.
- Private and Tor tabs cannot be in a group.
- A tab in a split view shares one group with the other panes. Moving one pane to a different group moves the whole split.
- Groups and which tab is in them are saved when you quit and come back when you reopen Acira.
- Rewind remembers a tab's group. Restoring a tab can put it back in its group, and Restore group brings back every tab that was closed with the group.
- In a locked workspace, groups are sealed with the tabs while it is locked. You cannot move a group into a locked workspace: Acira says Unlock {name} first.
- Moving a single tab to another workspace takes it out of its group. Moving the group keeps it whole.
- If you move a group to a workspace that already has a group with the same name, the moved group is renamed with a 2 after its name (then 3, and so on). Undo brings back the old name.
