Thanks. Well it's only intended to be a working solution until a better native app is made. Likely Kaidan will fill that spot in the future.
But I'll likely still make some improvements such as a nicer login page and a dark mode.
Given the limitations of the current HTML5 app support in UT, I have shelved more advanced plans.
I just hope the switch to IndexDB that is happening with ConverseJS 6.0 isn't going to break it on the old qtwebengine UT uses.
