Painter 2019 - Krita 4.1 released

It seems to be some kind of fork of Medibang Pro. Looks and feels the same but has a couple of different options in the menus and brushes.
If you delve into the brush engine you can actually create some pretty good blenders, but really I mostly use it for just doing quick colour/level adjustments or resizing and it loads up instantly which is what I need for that kind of thing. Although you do have to do one pesky click to dismiss the ad, but it's no different than a normal splash screen.

And it apparently does have clipping masks now that I've looked for it.

I still won't use them though.
