I like to import settings and I kindly ask you if there are any paid settings to be used in full like Photoshop as I do not like to figure on my own.
Example: Manage Import bundles...and all needed stuff.

No, everything is free. You can find some bundles and resources that are paid (like Digital Atelier), but there are not a part of a program, they're just resources made by other people. There are no hidden paid features or settings anywhere.

If you choose to buy Krita on Steam or Windows Store, you can get automatic updates because of the way those stores work, but that's another thing. Krita doesn't do it on its own.

For example, if you use Linux, you get semi-automatic updates for free because of the way Linux repositories work.
