Useful adjustment layer: Hue editor (The curve icon reflects the custom curve

Lots of useful adjustment layers actually.
ctrl/alt + space + click zooms in/out with every click
space + ctrl/alt + click reverts to the alt/ctrl binding after 1 click
.. but can I initiate a click and drag zoom somehow? That's always nice to have with tablet&pen
The mask/lasso/selection issue became clear, once I had the channel panel open next to the layer stack.
masking/clipping is on another level here.
not a lot of presets. At least a handful for every item would be nice in order to get a better understanding. Is there some thread here or a webpage with collected scripts/presets/window layouts? And is there a gallery thread where I can look at the works of other users?
performance still stumps me. In a few cases it is a little slower than PS, faster in some others and miles ahead of everything else I've tried so far...
Some options are spread all over the place while not being integrated in the context menu. Can I adjust that? Layer management (save/load) and ordering (send to back) for example - I'd like to have those in the layer context menu. I'll end up with actions and shortcuts anyway but I am not yet in the customization stage. Need to explore more first.
