Is your feature request related to a problem? Please describe.

When opening Fugit2 and you have a lot of changes it would be great, if hitting space on a directory would add all changes in that directory to the commit (similar as lazygit does it)

Describe the solution you'd like

see above

Describe alternatives you've considered

not sure about alternatives though. Maybe another keybinding.
