I was eager to try this. The screenshots had me convinced the workflow would resemble Alfred/Spotlight. Be careful of guessing your users workflows - there are a lot of ways using git. It seems opening the commit window stages all changes. I'm used to working with patches (`-p`), so in in it's current form it wont suit my workflow.
How is this a command palette? It looks like a single dialog, if I’m understanding the description and screenshots correctly.
To my understandings it's not a command platte, but has a similar workflow of "Bring up an input with shortcut → Type → Sumbit".
