Second suggestion which I'm not sure if it's too big for 7.5 or not, is a poll overhaul. It's irritating that have to hit a vote button for each question you add to a post.

I liked the 6.5.x way *A LOT* more! One post, multiple questions, one submit button. Actually shouldn't be to much work, it's just the voting screen that's need adjusting and the vote processing to process more questions and to reject non-complete votes.

Part of the poll overhaul could be to store both the USER_ID plus the IP address of a voter in the database.

Now it's a shared field, with just IP adresses of anonymous users, but to detect double votes from users, I would sometimes like to check on the IP address of the votees.
