Okay, that’s a nice suggestion. I was thinking to try to keep the UI more generic rather than integrate it with operating systems, but an Android widget might not be too hard to do, I might investigate later.

I do know Node, but I am not skilled with PHP, I haven’t used it for 10 years and I’ve noticed that things have changed a lot since the version I knew. I feel NextCloud is a bit overbloated, but I didn’t think about checking how they handled the communication part, that’s a good idea. It doesn’t overlap much with what I had in mind, but I might still be able to learn something. Thanks!
