Should be able to view hot / cold from the text view in deals. Instead of having to go in to the deal and vote. Would get more things voted and seen.
Obviously only downfall would be are some deals may seem cold from title, but explained better in description and thread itself.
Also, for example if a certain website has a code off, then we seem to get 10's of posts for different products using the same code. It's obvious to me that you can use the code for all these products on the site that qualify. Therefore some kind of sticky thread, or category to put all those deals under would be a good idea. Or even listed them UNDER a thread of a voucher code. So when a voucher code is posted, the good deals with use of the voucher code would be in that thread, as seperate threads.
Just a thought.
