Welcome
For bugs or feature requests to be considered by the developers, the recommended process is to open an Issue on GitHub. Some people discuss things in this user forum to get other ideas first.
Not all OH developers are part of this user forum.
I would avoid filing bugs on OH3 that might be obvious since there has not yet been a stable release. The best thing there would be to post in the proper discussion thread. The current one for Milestone 5 is here.
There is a new thread looking for language translation assistance if that appeals to you.
I personally get involved a little more “behind the scenes” helping with the Z-Wave device database used by the OH binding.
