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

There are many permutations of a status/staging view like the one in this plugin and out of all of them I still think this plugin does it the best. If you compare to Neogit for example, it's noticably slower in Neogit to stage/unstage files, more awkward to navigate (IMO) and slightly more awkward to view diffs for files/hunks.

However, where Neogit shines IMO is that it supports adding popups and commands. e.g. I have the following:

• In the pull popup:
  • The ability to pull from main (p m). Very useful
• In the commit popup:
  • A custom commit command which first runs a small script that chucks the diff at an LLM to generate a commit message
• In the branch popup:
  • Create a PR (calls a random go binary we have for creating them on ADO)
  • Create a branch based on a Jira issue number (uses the Jira API)
  • Open the Jira issue for the current branch
  • Might be more that I'm forgetting

As you can see a lot of them are super bespoke/tailored to my use-case which makes the ability to extend Neogit the perfect solution for this kind of thing.

Describe the solution you'd like

It would be great if Fugit2 exposed a similar API for extending behaviour so that we could further enhance what it's already capable of

Describe alternatives you've considered

Using Neogit :)
