Hi PackElend, thanks for asking.
I am having a pretty good time contributing. The PR I said I was working on is almost good to merge.
I have started working on the second part of this issue i.e. adding filter for plugins on desktop. Discussion for that can be found here. I will soon make a PR for it.
I have updated font-size-shortcut plugin which I hope to publish soon.
If I need any help, I will let you know.
Thanks!
