The SmartGit provides two ways to change highlighting scheme: first in preferences, second in edit window by clicking 'Syntax language' under view menu.
Both are not convenient enough in some particular cases. The first one is requires setting up for all formats you could have but not only standard. The second one requires too many actions.
Also in these approach there is no way to quickly change scheme from 'Changes' area. So the common way for 'Editor' window and 'Changes' areas expected.
The way how it can be improved to be more convenient:
1. Right click on diff panel -> Mouse over Syntax highlight -> Pick scheme. (Example from Sublime Text 3)
) (Two clicks one move)
or 2. Right click on diff panel -> Syntax highlight (opens window) -> Press '<Symbol>' for quick search-> <Symbol>scheme -> enter or Ok click.
or 3. Combobox somewhere in changes area with possibility to select scheme + Press '<Symbol>' for quick search
The handiest one is the third. The first one is on the second place.
