Separate snapshot.auto-track setting for gg

[lgarron]

I'm a great fan of gg and keep it open all the time while coding.

What I would love is for it to stay in sync without affecting repo state:

1. Either:
   • Have gg auto-refresh when the repo changes, even when it doesn't have focus.
   • A simple way to notify gg that the repo state has changed, without relaunching.
2. A way to tell gg to switch to another repo, without relaunching.
3. A way to prevent gg from causing a fork in the op log.

Currently I work around these as follows:

1. Re-focus and unfocus gg using a script.
2. Quit and re-launch gg using a script.
3. No workaround.

The last one is a real sticking point for me. I'm regularly seeing data races and corruption — even when I have my scripts carefully set up not to refresh gg until snapshot changes are done. In any ideal world, I'd like to able to run gg out of the box and just keep an eye out on repo changes as I work in my editor. But I'm getting forks (and merges) in the op log all the time right now. This in turn prevents jj undo from working, which means that it's often a pain to try to debug corruption from race conditions.

There's probably a proper solution to this, like having a daemon coordinate gg and the commandline or so.

But as an incremental step, I'd love to see:

• A way to have a gg-specific setting for the functionality of adcae41 specifically without disabling auto-tracking for the jj commandline (so that the latter can update and the former can view those updates).
• A way to trigger a refresh without snapshotting (although I can still kind of live with my workaround of focusing and un-focusing).
