Thanks!

Well, we simply don't really have a burn/dodge tool yet. I'm not sure where to fit it in Krita's current design: it could be a separate tool, or it could be a paintop, similar to the brush, pencil and so on. In the first case, it would be possible to burn & dodge with a soft brush or a hard pencil, or with
the airbrush. In the second case, it would be possible to burn & dodge in straight lines or across a vector path.

Yes, painting with filters is cool -- but it's not what you want. You can use this tool to add extra redness, for instance, or paint sharpness onto the image.

Well, we need still to write that section, I suppose. I'd need to dive back into the code for that, though. But it's basically just applying the chosen filter onto the area covered by the brush -- that's all. As if your brush area is a temporary selection.
