I see a future in jj

One thing I've wanted is the ability to group commits into a mega commit. So the history of little changes remains, but as you are scrolling you don't see all of them.

This is an interesting idea... jj has a templating language, but it's not stateful, so you couldn't like, hide some commits based on other commits, for example. But I'll file this away...

You could probably use bookmarks for this.

I've thought that it could be as simple as commit's with a message beginning with "minor:: " do not get shown by default.

Hmm, yeah that might work. I was thinking about grouping all “minor::” commits as one commit, but this sounds more feasible.
