Thank you very much for this additional info, but unfortunately, I'll have to skip Procreate for now as it's built primarily for iOS, although they say it's one of the best such programs out there if not the best.

I made some additional digging around to see if there is a way to use it on PC (Windows), and I even found the way how to do it, but unfortunately, additional software needed and all this workaround would drain a bigger portion of my RAM and disc space which I'm not willing to "sacrifice" at the moment.

I'm considering now Krita for which they say it's a second-best Windows alternative for Procreate, and an entirely free, open-source program. The only cons might be some time needed to learn it, as it's described as a professional-grade drawing program but with tools that for an average user could be overwhelming, or in other words not so intuitively easy to use.

But we'll see how much time I will have to invest in learning it.
However, thank you again for your sincere help and advice! 😀
