Discussions Optimizer Enhancement

So, my previous suggestion received huge feedback (176 Yes votes), and eventually was implemented by super awesome user Ruphine (praise him).

So I hope that if this topic will be given enough feedback, and Yes votes - some awesome person will do the script\tool to implement this features, as Ruphine did for Steam Gifts Tags - that is currently available - here.

I use steamgifts discussions A LOT, and sometimes I miss important topic or it's update, so I came up with few ideas (sorted by the order of importance):

1) Ability to hide, and mange hidden discussions, as you can do with GA's
2) Sort discussions by created date, so you will never miss on new discussions, currently they are sorted by last reply
3) Show Recent Discussions only, and you can set time period for example - only discussions created for the last 24 hours or 30 days
4) Chose what categories you want to include when all is chosen for example if you want to see all discussions except off-topic and Let's play together.
