Potential improvements to Inherit Alpha in Krita

[Deif_Lou]

This is a mockup based on my previous comment (icons were made kind of quickly and can be improved):

Another ui possibility just occured to me: The inherit alpha button just enables/disables the clipping. When it is enabled it clips to the layer bellow only, and the layer is indented a bit, showing the down-arrow on the left. Then, if the user clicks on that arrow, the mode alternates between layer bellow and all layers, and the arrow icon changes a bit to reflect the current mode.

• 1st image. No layers use inherit alpha.
• 2nd image. “Paint Layer 2” is set to use inherit alpha. The default mode is “inherit from below only”. The layer is indented and an arrow appears to the left of the left of the thumbnail.
• 3th image. The user clicks that arrow to toggle the “inherit from all” mode. Clicking again toggles the “inherit from below only” again.

At any point the user can deactivate the inherit alpha with the button but the mode is stored, so that if you activate inherit alpha again, the layer will use the last mode you set on it.
