I did discuss your concerns in the email above with the team. A number of them have been worked on. The rest I felt were not a priority in the context of our other plans.
Are the Chat keyboard and pagination issues still a problem for you? I seem to remember that you use Brave on your phone? It's not a browser that we do any testing on, so it'd be good to know. We overhauled the whole Chat feature, since your email above. You might have noticed that it is a lot faster this year. I recall that parts of the work specifically tackled the Chat problems you were experiencing.
Although not a priority, the favourites ordering is a 30 second fix that we can pop into the next sprint.
You're welcome to report the forum related bugs to our forum platform here. Matt is regularly threatening to migrate the forums to another (more modern) platform, so maybe he'll convince us (and himself) to go through this schlep in the nearish future.
Between Intercom and the forum threads, I feel that we do fairly well at keeping track of bug reports.
I use the Now-Next-Later framework for roadmaps. But I fear you're looking for more precision than that for ticket tracking.
If any of this a dealer breaker, let me know so I can proceed with the account deletion.
