G'Mic has many wonderful tools. However, they are not well integrated in krita. In particular patch/inpaint tools are quite useful for editing, but really hard to use in the current setup.
The idea is to create a brush or a tool that would act as content aware patch tool and make it accessible through left side tool box.

I would have to rewrite G'Mic algorithm to use "krita way" instead of shuttling bits between krita and G'Mic formats.
