Well then like I said, Atmosphere (ie SciresM most likely) is planning to reimplement the entire FS module in source, which will enable what you want to happen, and the reason he hasn't done it yet is because it's the biggest fucking module and he's been quite busy reimplementing the rest of the entire operating system. Given that, it's clear why he wouldn't have spent any time doing things as patches instead. To me these seem like good reasons why other skilled devs might not have chosen to sink huge amounts of work into patching, when waiting will get better end results, but I can't speak for every dev out there. The only devs that already did do all that work did it for the grand motivator, cash money, so have you tried offering to pay anyone?
