I hope you're doing great. I'm super-excited to tell you that I've just released a new extension panel for Photoshop: Layer Factory.
Create new layers with blending modes of your choice, create new adjustment layers, layers from selection, symmetrify layers, move selection of several layers simultaneously, convert opacity to layer masks: it’s all Layer Factory! I've been using it every day for.. some years now (yes I'm slow to release things) and it's a huge help to me.
As always, if you have any questions, reach me at firstname.lastname@example.org.
