Just a weird thing that happens- when accidentally eyedropping on a transparent part the brush doesn't paint anything (which kind of makes sense) but when toggling to eraser mode the eraser doesn't do anything either. Perhaps expected behavior would be to keep previous brush settings when clicking on a 100% transparent area, or at least allowing the eraser to work. Thanks

I guess it should be renamed into something like "Disallow painting with totally transparent brush" :)

I like not doing anything when color picking a transparent color better.

Pushed by rempt into branch 'calligra/2.8'.

The opacity of the current fg/bg color is handled by the opacity slider,
not by the current fg/bg color. I checked what photoshop does, and that
also doesn't pick the alpha when picking a color.

The issue comes up only when picking a completely transparent section (by accident of course). Gimp actually makes the color black when picking the 100% transparent area, which maybe makes sense when dealing with alpha channels?

Yes, the same now happens in krita. Still need to make new Windows packages...
