Hmm, I think the latest version of UrW should've fixed that problem with 100% CPU usage while idle.

At the moment Discord is the best place to report bugs and to post feedback / suggestions. But if you prefer not to use Discord, e-mail is also fine. But, yes, I need to think of community platforms in the future - at the moment I'm happy to keep it somewhat limited, for it easier to concentrate on the development if all the feedback is just in one place + e-mail.
