I know it means you’d have to learn all those things … and … you “can’t be bothered”, you’d rather stick with PS … I’m not saying that’s wrong, just that the statement:-
It's not that "I can't be bothered", it's the fact that it means learning a whole new program, it's shortcuts, how the layers actually work...
contradicts itself 
The rest of your last response was ALSO just another way of saying… “I can’t be bothered, I already know PS and don’t want to spend the time to learn anything else”… it’s ALL based on having to learn the GIMP interface, and not wanting to.
You use terms like “VERY differently”, “have to learn”, “figure out”, “I don’t think it would be like Photoshop’s”, and “finding another way” …
Your other problems are things like the background layers aren’t locked by default ? … really ? … lock them then.
It’s just a different way of doing things, and things are in different places (including mask and scripts) … learn where they are and how to use them.
I’m glad that PS in WINE is now working for you, but can’t help but think the time you spent trying to get it to work may have been better spent learning to use something that will work “properly” in Linux, and won’t waste more of your time the next time WINE is updated … after all, “Time is money” 
I’m just pulling your leg … but call it what it is, you can’t be bothered to learn the GIMP :-*
If you can’t be bothered to learn the GIMP, or NEED a feature that the GIMP doesn’t provide … not a problem … use Windows and PS.
Though the GIMP will quite proficiently do most things that PS can do … it does do them somewhat differently.
What I’m saying is that IF you must have PS, then a VM or dual boot is preferable to wasting your time on an app that is at best “flakey” in WINE
