Even writing it out in more detail will not suffice. In the end this has to be tested by somebody of the Krita team. Then a decision can be made if it’s worth implementing. And if the description was too short, I can always provide a bit more information if needed.
It’s a “docker” where you can throw all kind of things into. Brushes, erasers, other tools, commands, actions … Maybe there’s already something like that in Krita.
Mine looks like this …
It’s about the same as the masked brush option in Krita. There might be more options in CSP or maybe they are just different. One thing that I like in CSP is, that I can assign multiple brush tips to the “masked brush” at the same time. In doing so I can make those pattern more dense, lighter or different looking quite creatively. But that’s not the most important thing. The masked brush in Krita is fine as well. Should easily cover the options that Photoshop has got, which are very basic.
It’s a “docker” which contains brush-specific options. Which options are in there is up to you and you can show or hide them via the brush settings dialog. So it’s not a popup - it’s there all the time. This makes very usable. No extra clicking.
Here’s a example for two brushes (same docker - just different active brushes). On the left is an inking brush, on the right a rough concept brush. For each of those brushes I defined which settings I want to see in that docker. At any time I can add even more or remove some of them.
I hope this makes a few of the things clearer.
