In the meantime, however, I am almost at the point of creating something myself.

Wow, that's a lot of work. The main thing is that you were interested in doing what you do :-)

But before I touch the design again, the functions have to be ready.

I absolutely agree. In addition, in order for your design to be more attractive than the standard one, you need to think about which features you currently lack in the standard design. Then, if possible, implement them in your new design.

Thank you for your attention and your answers.
