Locking of Layers like Gimp

Hey Guys,

I often run into the Problem, that I accidentally draw in anotherlayer than i was expected to draw in.

It would be very sweet if the Layer view would inccoperate a lock layer next to the visible icon like in Gimp.

If you can hide the layer instead this will also prevent you from accidentally editing it. But eventually we should probably add layer locking as well anyway. The following github issue exists about this:

Thats cool :slight_smile: - so you can see the other layers without accidentially draw on them
