Hello
i can't modify or create a MyPaint brush preset. As you can see in the picture i've created a folder on the user home for the main brushes of MyPaint with the rights to write but the editing buttons on the frame are still grey.

Correct, you can't , at least not using Gimp,  MyPaint brushes are quite complex and are best edited using the mypaint program.  Next snag is Gimp is still using MyPaint type 1 brushes, so you need a MyPaint 1.x installation.

This a Mypaint 1.1 in a Windows VM to modify an existing brush. It saves to C:\Users\your_name\AppData\Local\mypaint\brushes
Then in my kubuntu Gimp 3.0.4 appimage - make a folder / path for your bespoke brush in Edit -> Preferences -> MyPaint Brushes

   

hmm, I need more practise.

As a heads up, in the source code and officially starting in GIMP 3.1.4, we've ported to MyPaint version 2 brushes.

@Scallact

An alternative for  making / editing and I have never tried it.  A MyPaint brush is a text file. You should be able to make adjustments using a suitable text editor.

@rich2005, this seems to address OP's question, so I guess it's not intended for me...
