"Why is this feature still not added? It could be done in a few hours" is one of the most annoying things you can say to an Open Source dev.
But okay, let's say you're right and it's "just a few hours" (shall we say 2?). Then there's still more than 50 other open issues, if they're all "simple" and "just a few hours" that's at least 100 hours worth of work of things. Everyone claims their request matters most.
Also, am I allowed to, you know, have a life besides my side projects? Please?
