Any custom made software is pretty high up in the list. Whenever I build something myself I always start looking for ways to move to something off the shelf.<p>Anothrer big one is browsers. I use Kiwi+Chromium+BitWarden sync, but I'm not completely happy with any existing browser. Nobody has an open source full-featured chromium with sync, and nobody so far has a practical decentralized web platform with any traction.<p>I would <i>really</i> like to get rid of the Thonny IDE. There are no good tools I know of for working with MicroPython, uploading code to boards, updating firmware, etc. Just piles of command line apps, and no mobile support.<p>I would also like to get rid of... basically all the methods of building an android app. Kivy's buildozer is great, KivyMD is still rather unpleasant to work with.<p>All the existing methods of making Android apps seem to involve ugly hacks to get UI working, and a lot of hassle to do stuff like background services, Bluetooth, and serial.<p>I suppose that goes back to browsers, since making more things as PWAs and browser extensions will probably be the solution for this stuff one day.
