Arduino libraries that need to be written and/or improved

Hi

I have written a few Arduino libraries and would like to write more, looking for information.
.

libraries that need to be written?
Components/modules that do not have libraries?
Existing libraries that need a major improvement or new features?
Any other forum or site where to ask such questions or find info?

Regards

what category? what architectures?
