That's a really cool idea that I never thought of.
One of my concerns would be that now you need every developer on your team to install this to their browser, but if you're working alone, this could absolutely be an easy solution!
I saw it working with teams too, it becomes part of the onboarding, and as soon as you have one feature used everyday nobody forgets (or anyway everyone else will remind you soon enough).
on the same note: it would be nice if you could add buttons to a readme.md which trigger the actions, maybe via https://www.actionspanel.app/, but also the buttons then are in the repo?
We've thought about this feature actually. What we haven't quite figured out is how to deal with the authentication of making sure that someone SHOULD be able to run the action.
That being said, on the website, we do give you a markdown snippet to add to your README to make it easy to navigate to the correct page of your repo in ActionsPanel
