Why is switching from one layer to another included in UNDO

[Jen-Jen]

It's annoying when you want to undo quite a few steps in your project, art, photo whatever it may be, that switching to different layers or making them visible/invisible is included in the undo steps.
You make layers visible or invisible to compare the artistic steps you've taken, it's a visible thing not an action that you've taken to the project itself.

Is there a way to not include that in the Undo steps?

Hello Jen-Jen,
sorry, I'm not aware of a feature to disable this behavior. It disturbs me too. (Corel could improve it, by considering just the last selection or viability state, if there were several selection/visibility changes in a row by the user.)
Let's hope for better times.
Friendly greetings

You can't turn it off but you can speed up the undo by using the history palette. Just click on the eyeball next to the last step you want to undo and it'll undo everything up to and including that command. Or get used to hitting CTRL + Z after hiding a layer or switching layers instead of showing them or re-selecting a previous layer. Using the History palette also offers some unique options for how things get done.

For example if you CTRL + Click on an action you can remove just that one step from the process so it's like it never happened, leaving all recent changes alone. Do this on a "Select Layer" command and suddenly all of the painting you did on one layer moves to the previously selected layer. At most having to undo a layer selection is annoying, but I like it. Maybe I've just been using PSP for too long but I like it.
