Replying to Are there any other Photoshop tweaks that are worth knowing?

I consider myself to be decently knowledgeable in ps, I know that basic "CLR" crop, level & rotate. I know about curves, how to use the spot healing and clone stamp tool. I know the basic methods of selection and how to use all the selection tools. I know how to make panoramic shots. I know how to use the pen tool. What I'm wondering if there is anything else worth knowing, I have looked at some actions but they all seem kinda "grade 8 lg photo booth shit" If someone could point me in the right direction towards any useful actions that would be nice. Do you guys do anything else to your photos in post? I'm interested
