Hello!
I love this program, I think it's a lot better than Photoshop in most every way.
I have ONE problem and it's for digital artists like myself.
You cannot "hard lock" a layer to where is it completely ignored and unaffected by the mouse or a brush.
When I lock a layer, I want it to remain exactly how it is forever unless I unlock it.
It's super frustrating to accidentally select the locked layer and draw on it, and have to remove all of the work you just did because it was on the wrong layer.
Please change this feature, or at least add two types of locking states for each layer. I can't tell you enough how helpful this small change would be.
