When I'm working with masks and the cursor is leaving the image area, it changes into a standard cursor instead of keeping my brush settings (size, opacity etc.). This cannot allow me to start painting out of the image and enter into the image with desired opacity, sensitivity etc.
See Apple Aperture. They did it really good with idividual tool / sliders and auto open/closed HUD workspace. Capture One already looks like Aperture, and they've been slow walking more and more of their features as time goes on. Would've been nice if Apple sold off Aperture to a developer so they could have continued it.. but here we are. Capture One is closer now than ever.
