Alternative ranking of suggestions based on community pricing
Include in the UserVoice system an option to pay toward moving a suggestion to production. By this, I mean that if a suggestion is vital to a limited number of users, it may not be able to gain enough votes to top the ranking list; yet, by incorporating this suggestion, the idea's production could still be ranked according to how vital its supporters find it to be. Upon gaining enough "funding" votes, it could be then treated as a Pre-Pub item in production, that, when completed, would no longer cost money to users.
I would rather not pay for features that I hope would be included standard, yet would "put my money where my mouth is" in a heartbeat to gain a select few features that I hold dear.
