Got to agree with
@linkinworm I think the design needs looking at as currently it's rather dated looking I'm afraid. Your theme is amazing so hopefully you'll not be offended but I think you need some help on the graphic design side of things. Of course good design is subjective but if your in anyway open to ideas I'd say this: Especially with the limitations of the GBA resolution - for it to look modern and clean - you want to lose all those rounded effects, any shadow or shading effects and go for solid and single-colour icon shapes. Then for highlighted text/icons use one high contrast/non-clashing accent colour. I'd start with the theme
@linkinworm attached called 'clean' which is by far the best I've seen yet - and build on that with the simple but effective colour schemes used on the Nintendo Switch's Light and Dark themes. Some people may find it boring - fine, some people will always want to have a messy theme based on their favourite band – but most people prefer UI/UX design to be minimal and clean these days so it doesn't interfere with their content. Your san-serif font is nice btw.
I also have some idea's for how I'd do the startup screen - using a nice clean Omega symbol and nice text to make an unofficially Logo - again not dissimilar to the Switch Logo/any other . I wish I understood better how to change a ezkernel.bin and I could have a go myself and show you it to see what you think, if you were up for it?
