It’s not based on Ultimate Guitar but Tabs Lite is great, has pretty much every song I ever searched for, and is available on IzzyOnDroid.

Your proposed solution to overly complex systems seems to be to ignore the requirements that make them complex in the first place. If that works for you, this is a perfectly fine approach. But most companies with actual signed SLAs won’t accept “we’ll just have a few seconds of downtime/high latency every time a developer deploys something to production #yolo”.

I didn’t get an answer, but I’m now pretty sure it’s not possible yet.

The only possible answer is House of the Dead, followed by all other Uwe Boll movies.

Say I never read about these news: am I able to somehow see that a community belongs to a defederated instance, or do I have to guess based on the (lack of) new activity?

I have a feeling you’ll enjoy Iosevka then.
