This issue might be adressed allready however,

for those of us with less powerfull computers creative flight is a pain because we literally can't fly whenever there's a bit of client lag going on, adding an option to add non-creative flight (as in draconic evolution chestplate, or jetpacks) would be awesome.
thank you for your time

Ummm, I can only assume you're talking about how the double jump to initiate flight doesn't work when your FPS is too low? I have a really bad PC myself, so I run into that a lot.

Anyways, I'm not implementing an entirely new flight system just to cater to low-end computers. Sorry.
