I really don’t know yet. Maybe another front-end is a good idea. I am aiming for a clean user interface that is easy to use. Really i just wanted to show you how far my progress is and what other people think of my design idea 🙂
I personally am quite fond of the grid pattern gamelist instead of the gamelist like it is currently. Emulationstation had plans for a grid pattern but never quite got to it before real life got in the way.
A minimalist design is the way it should be in my opinion. Kodi has done a very good job with their layouts and theming options, game frontends are a bit behind on that front. There is also this one that you might be able to adapt: https://github.com/RetroPie/RetroPie-Setup/issues/1071

I’m not sure your level of coding experience or if it would just be easier for you to find something that’s already built and just make a theme for it, but I like your preliminary ideas 🙂
