Hello,
I just can't figure out how to get rounded corners on the notification icons. It currently looks like this, but I would much prefer it to have rounded corners.

Any help is appreciated!

@julius-boettger I've been thinking of adding this myself, so "should" be on the chopping block after I've merged the grouped notifications PR :)

Sounds good, thank you! I'm looking forward to using it once it's out.
