For that purpose we use a separate dedicated command: "Modify or Split Commit".

Simply hiding untracked files is no option for you?

For this use-case I'd rather would request to allow to unselect the branch "anchor" from the Commits view.

I reckon, this is not possible with the used GUI toolkit (SWT). And what benefit it would bring?

You could give it a try: https://www.syntevo.com/smartgit/preview. The portable bundle contains Git and the bundled Git contains LFS.

Have you already tried SmartGit 18.2 preview from https://www.syntevo.com/smartgit/preview?

Please send the repositories.xml to me (smartgit@syntevo.com) and let me know the new repository location. Maybe there still is some bug.

You surely know that you can drag and drop the views. The default layout in 18.2 also has changed.

We remove the default accelerators F8-F10 in 18.2 preview 8. We intentionally added no 3rd state because we think it rather an option to work either in the mixed mode or in the working-tree vs. index mode.
