Well, vote system won't help, because Nomad have one priority user - me. And wishes and ideas of that priority user implemented first.
You can, however, ask for features you need, if I found them easy to implement or interesting for me, they will be implemented (right now I'm working on some features requested by only one user, because I've found them interesting and challenging).
Another option is to write your own plugin implementing functionality you need, of course that option is not for all, and not everything can be implemented that way, but still, I believe time I've spent on implementing plug-ins framework was not wasted.
