It is so great that you are working hard on there, but as you can see from replies some work is still needed. Like to mention one crazy bug you have not yet fixed:
Start calendar week on monday (or allow setting)
You might ask from yourself, how costly it is for Microsoft to keep two different calendars for Teams up to date. Outlook has done great work with calendar, so do you really want to investment to get a new wheel?
But the thing I really wish to see to get fixed is Release Notes for Teams. See e.g. how good work the Room System team does and what do they share for us:
Release notes
They share three things: date, version, and changes. So big thanks to them, who ever they are!
You do almost the same, but as you can see from: What's new in Microsoft Teams we are missing the version number. Without version number it is extremely hard for us to follow what has change in which version and set our expectations.
I'm not sure if this going to be change when Teams flies into Office 365 ProPlus. See: Release notes for Monthly Channel releases in 2020. But at the moment we are close to blind.
