Move official suggestions list to bug tracker/poll
I've seen it on other systems where people can vote for changes they'd like to happen next (or bug fixes). I'd think that could be valuable for you to help prioritize what people want without requiring you to read through and tabulate new forum posts as much.
What I saw in the past was that each registered account could add their 10 votes to a single entry, or to up to 10 entries. And when those were done they could reapply those votes somewhere else.
