Layer Transparency lock and Layer grouping.

Hi! I've been soo happy using PyxelEdit more and more these day
And found that layer blending mode allowed me to make variety of technique I able to do with ProMotion's multi-shade. If PyxelEdit have a traditional layer transparency locking or better, able to create layer mask from selection it would be a awesome and allow artist to do even more trick and technique on the asset. So, please consider adding this feature please 


And Layer list on current version has some bugs >> sometime when you have a number of layers that filled the list vertically, when you scroll the list up/down it will cause layers on the list disappear. And you have to nudge the list border around to make it come back.
Thanks!

Yeah, this would be a nice feature. I have considered adding transparency locking, layer masks would be a bit more difficult though but might be doable...
Thanks for the bug report on the layers list, I will look into it!
