I want Krita to start up in the following way when I open a new document:
- _Basic-2_Opacity brush shoulde have a size of 3px
- _Basic-1 brush should be in eraser mode
- _Basic-2_Opacity should be the selected brush, and I should be able to switch between the above mentioned two brushes with the slash key
- The background layer should be filled with a grey color

Is there any way to achieve this? Like creating a template file or scripting?

I'm new to Krita, so sorry if similar stuff was asked before.

Thanks for the help!
