Kyatric is right: both Tom and I have tonnes on our todo lists right now, and when people make suggestions often lots of people suggest something which is already on our todo list, or they suggest such large projects we would not be able to realistically start them for 6-12 months, by which time we'd have even more suggestions...
Obviously listening to our users is vital to what we do, it's just the problem is we are a 2 man team and we've become totally saturated with amazingly cool ideas we can't wait to work on. So we're basically going to be crazy busy for 6 months! Like that other post says if you have little ideas for tweaks or minor changes, we can usually sort those out - just make a new thread for each one.
I'm also reluctant to publish our todo lists, because they change frequently, sometimes we realise ideas were bad ideas, should be done differently, or the priorities are changed etc. So I think it would be kind of misleading if people came to depend on it to know what's coming next.
