[inasmuch]

> The new save dialog is insane. No, I don't want to save a copy just because I want to save a jpeg. Why is this even a question?

I don't like the new save/load stuff either, and much prefer the old versions you can toggle, but that does bring up the fact that /you can toggle stuff/ and really customize the app to your preferences. I don't know any other visual creative tools with the depth of customization that Photoshop affords, between the fully modular GUI, actions, etc. A side note: jpgs saving as a copy has always been the default when you're working with a psd. There used to be a way to turn off the 'copy' appendage (like you can when duplicating layers), but I can't remember if it's still there.

> I know you can duplicate a layer - but not to a different document.

You can, actually! Been able to for a very long time. Right-click on the layer > Duplicate layer > Destination > Document. Pick another document you have open or create a new one with that layer. Pretty handy!
