Are there interface patterns for programs?

Question

User interface

Hello.
I've been writing a program in PyQt for a year and a half, I'm coming to the end and I started thinking about the interface.
Convenience, beauty, interesting ideas.
I decided to search the Internet for ideas, patterns, pictures. It turned out that there is almost no such thing! There are thousands of sites with templates for sites on any subject, but I haven’t found them for programs.
Maybe I'm not looking for it? Or is there really no such thing?

Answer 1

There are, they are called UI kit or UI psd , which is often the same thing. These are sets of interface elements from which you can create any of your own.
Less often you can find a directly assembled interface, but there are very few of them.
If you are looking for inspiration or finding good solutions for a user-friendly interface, then just look at real software and take the best. Templates will not help in this regard.
