Paintbrush with eraser ability

To use the same brush to erase a stroke with a toggle short cut (recursive). In MyPaint and Krita is possible to use recursively the two tools using only the key 'E'.

To make this in the current stable and development releases we must follow this flow:

1. To share the paint options between tools
2. Change between the P or N key with Shift+E and again P or N (for instance)to follow painting/drawing.

The process that is possible is a bit unfriendly if I do a comparison with the flow with Krita/Photoshop and MyPaint. Have a toggle or recursive key to make this, it turns this action more easy and fast to execute. Imagine the users that are using a graphic tablet with GIMP... is necessary stops the action with paint tool, and to use the hand (left/right) to invoke the eraser, with Shift+E, and after again, 'P' or 'N' (for instance) key to follow using the paint tools.

I think that the 'Paint Options Shared Between Tools' works fine in many cases... but not to all. My suggestion, here, is to provide another option to have the eraser directly on paint tool. For me and many painters that are using MyPaint and Krita, this feature is working fine. See thread on mailing list - ideas and suggestions around digital painting on GIMP.

Brainstorming and ideas

• A plug-in action (with a toggle key) to enable some blend modes on the paint tools to erase the strokes. For example, the paint tool with blend mode + foreground colour to erase the stroke/stain. I have tested with Addition Mode, with white colour as foreground and works fine to delete. The main question here is: we want/must eliminate a wrong stroke or many strokes (this is a simple task) or we need of the Eraser Tool to make actions more complexes? I am thinking that both flow options are important and convenient, but each of these depends what we are doing in each moment. Normally, during the paint sessions, we must to delete some wrong or undesirable strokes/parts.
