I've seen posts for these before, but if this works like a voting area, then the more these requests get seen the better...
My main request is a "System Update" option standard. One of the biggest complaints about Linux in general for Windows users is how hard it is to install something. Instead of clicking on setup.exe, you have to do a bunch of other junk. I think a standard interface (like devinfo-mitel-update-system) for adding updates would go a long way toward overall user-friendliness. If users are able to easily add updates themselves, that puts less pressure on Mitel to add more stuff to the basic distro too.
Port forwarding isn't quite as important, but a lot of people do use it. And it's not really a big deal to have it installed even if you're not using it.
