Thanks for replying! I didn't expect the lead dev to actually reply. I will certainly drop by when I find enough time.

- yes, this is self-hosted. I can't check the version, but I think it was recently updated

- notification emails in non-html mode don't carry over the bold, not even in the form of asterisks, so it all blends in with multiple messages

- the "drafts" feature took me a year to discover. Sadly, messages were recomposed. I think it's useful when the composing is interrupted due to external reasons, but not something to work around user action causing clears

- thanks for fixing the collapsing bug, I'll see how my opinion on the composing workflow changes

- CPU load is not that bad, but still way worse than my IRC client or a non-JS forum, so

- I may be somewhat unique in that I automatically `kill -STOP` and `kill -CONT` the browser when not using it, sometimes keeping it frozen for days at a time. That is causing the server issues. Notably, I haven't yet seen any other software or pages having problems with that.

One thing I always respect is the desire to keep improving! Kudos!
