I'd like to suggest something a bit different - to keep updating latest apps version to winget db. Many people use winget and install/updates apps through it. It's very convinient as it allows for non-interactive installation and updates. I've done it a long time ago for Nexus and Xtreme, but it was 25.7 version. Now users can't install nor upgrade it because installation zip file leads to the same URI, hance showing "Installer hash does not match" error:

Keeping apps up-to-date in winget db gives the impression of greater attention to the user experience by the devs, and it's extremely simple to do.

In case of UI being outdated, this is a bit ridiculous thing to say IMO, as preferences window looks very good and I wouldn't change anything about it, but if I can be extremely picky about UI, then I'd pick context menus. I've tried to make them myself to match Windows 10 and 11 looks, but it was too overwhelming for me, so I really look forward for full theming guide.
