Hello @cyanlos, and welcome to the forum!
Since you yourself said it already, so that you want to provide feedback, I moved your topic into the category meant for providing feedback, even its name tells that it is meant for exactly this.
For a few things of your thoughts, we already have plugins, like the original but in between very old ToolKit plugin and those plugins that incorporate it, like the mega plugin Touchify (download link to its most recent version, but that massive multipurpose plugin may overwhelm you), or modernized it like Toolkit Pro.
And I guess that you may find other interesting plugins in our forum category Plugins and Scripts - Krita Artists that will help you to create a different user experience for you and simplify things.
