Maybe you don't know, but you can add your own tools in the preferences.

Will be fixed in #20105.

To check out a branch by typing the name, you can use Ctrl+P popup.

Set the low-level property repository.suggestMostAppropriateGroup to false.

Would you mind invoking an extra action in the Commit view (or dialog) to trigger invoking the .git/hooks/commit-msg script?

In the next build there will be a low level property to show the path, too.

Works fine on our Linux machines (Ubuntu, Manjaro - both with Gnome desktop).

Drag the commits right beside each other, select them and invoke Squash.

Please describe your workflow in more details.

Works for me on MacOS 13.3.1 (M1) with SmartGit 22.1.5 and a real mouse.
