Interactive rebase

**Is your feature request related to a problem? Please describe.**
I'm also using Fork, and the sudden change of policy doesn't really suit me so I was looking for an alternative. The feature I use the most was interactive rebase so here is my feature request :)

**Describe the solution you'd like**
Ability to have a list of commit that I can act upon (squash, reword etc…)

**Describe alternatives you've considered**
I'm not really good at git CLI, always used a UI so if gitui could become a fully featured Git UI, that would be awesome.
