Yeah, it somehow escalated from a simple "how hard can it be" when I started few years ago.

With the testing of Valhalla update there isn't much we can do, I will have to do it myself. Main issue is to get a time slot for it - there are few things I want to finish first before.

As for help, picking up an issue and fixing it is the best way. Like done over here @TMO with icons, for example. The issues that you picked up are great, since I would not have had time/priority to deal with them in a while.
