Fast. https://github.com/emacs-mirror/emacs/commit/4a0958642d96fcd521087dc4fa54d0701797a585

Yes.

Perfect. How will you get that confirmation or should I copy/paste their response to me?

I've asked them to cc you and pasted your email address. Either way, I'll let you know. Thank you for your patience.

FYI, I added a defensive test in the mode before setting the timer, should someone set activities-mode-idle-frequency to nil (as I might).

I hear you. If activities bookmarks aren't long for this world, it wouldn't kill me. I prefer using the activities API itself vs. bookmarks despite them being a natural part...

Giving this a shot.

See #101.

Finally getting back to this. Pushed updates accommodating your comments.

Only json files with treesitter, so far. C++, Python work fine. Perhaps you could share your json-ts-mode set up and I'll see if this is user error.
