Heya BGK, welcome to TMO!

rinigus states in his description in app and on Github that both, this thread as well as the Github issue system are approriate places for ideas and wishes.

If you really need an advice, think of who is reading. This thread probably has more readers than the Github issues and is good to discuss, share rough ideas.
The Github issues are for rinigus to collect and roadmap because topics are much better trackable as this multi topic thread so i put important and long term things over there imo.

I can not make much hope for good looking glow effects though. But maybe you have a draft to share of how you think it could look good?
