Switch to a Windows App and Dump the Web App
The UI issues I have had (and have) so far with MM have been browser-related. Freezing that was caused by an anti-tracking plugin in Edge, Weird issues checking off transactions as I review them, account list being empty occasionally which seems to happen on Edge but not Chrome, issues caused by zooming out to get more accounts and transactions on the screen, etc. etc. Why not eliminate all this and reduce support requests by making a Windows app and dumping the web app altogether? It would make things much more controllable and make for a better user experience for Windows users.
Edit: Same with Mac OS.
