If you are using the Working Tree or Log window (where you can freely rearrange the views, you can maximize each view (incl. the Changes view) by double-clicking its header.

Hi Andrii, you can change the file patterns in the SmartGit preferences, page User Interface > Built-in Text Editors > Languages.

You may try setting the low-level property "completion.useAltAsModifier"  to true. Maybe that helps for your use-case.

Will be fixed in 26.2.

What operating system you are using, what system theme (light/dark)? Do you mean the auto-light/dark theme in SmartGit or the forced dark theme?

What exactly is hard to distinguish for you which was easy before? Please show an example.

Note, there is already a related ticket: https://smartgit.userecho.com/communities/1/topics/1887-better-distinguishable-icons-for-untracked-and-added-states

What exactly is hard to read/distinguish for you?

Do you just don't like these colors (e.g. because the color choice is ugly) or do you have so problems distinguishing the icons? Which icons - the toolbar icons, or the file icons?

Would that be an improvement for you?

The Standard window's Commit view will show branches, tags and on branches information since SmartGit 26.2.
