Hmm, I can see it when I'm not logged in (Tickets -> Feature Requests -> "Create Ticket" button"). But you're in luck! In the 2 weeks since you started this thread, I've moved the source over to GitHub, whose interface I find cleaner and more intuitive than that of SourceForge. You should be able to add a Feature Request here
now ("Issues" link on the right).
I'll be moving over the open bugs and feature requests from the SF site over to GitHub in the next day or two.
