Can't we already open kpp files in krita and pimp them to the bone ? Which explains of course why my brushes have the most shameful icons ever...
A very handy thing would be to be able to paste a preview from clipboard in a brush setup dialog ?

I do change tags when I'm constrained to, and I always feel cut in my workflow when doing this. Because I then get a brush and switch back to the first tag.
A nice to have would be a history of a parametrable number of last used brushes. Like we have for the colors history

I'm with the idea of providing a small (compared to the actual) and well rounded brush pack with which people will feel able to quickly do stuff. The most uncomfortable situation is to scroll accross a long list of useless brushes that are all the same, except...the green pepper brush. Yeah I'm looking at you gimp !
And for people to feel able to quickly do stuff, you need to showcase the brushes. David Revoy knows his stuff and he already made a very nice job of presenting his bundle.
I've always been very unfriendly with downloading a big brushset from a well known artist and get lost in duplets and useless garbage, no matter how big the artist is. But the deevad bundle is so well presented I went with it (actually it's the only one I got).
