Because it's weird to have to switch to another app (Finder) to do a part of the feature (Worktrees) while being able to do other parts directly in SmartGit.

Then maybe a separate menu "Delete worktree" that only deleted the files on the disk, and then prune removes it from git?

But it (SmartGit) could also `rm -rf` the directory, right?

It isn't completed. Selecting only a file and hitting cmd + s still stashes all the files. While hitting cmd + k correctly commits only the selected file. So the inconsistency still exists.

Removing a worktree would be nice.

It should also select the line on a single click, not only on click + drag.

It looks to me like it still computes the diff, and only after it finishes does it present the "File size exceeds ..." message. Because when I click the "Force Compare" button, it takes the same amount of time.

I know, but when I look at simple commits I want the list to be narrower, so I don't want to enlarge and shrink it multiple times. Whereas the main window's files list is already wide.

But the actual files list is in the small right side instead of the center of the screen, so it's a bit different.
