Viewing Workshop Subscriptions and Steam Controller

[Chaostraveler]

I've started using the big picture mode more now that I have a Steam Controller, an I noticed a few things that are a little annoying. First, I can't get my controller to scroll through any of the description boxes in the Big Picture store; I have to keep a mouse handy because that's the only thing that works. (Also, the steam controller wouldn't let me start this discussion. I couldn't click in the text boxes to start typing.)
Second, I went back to play Left 4 Dead 2 and I realized I couldn't tell if I still had any mods active since I was playing on a new PC. Same with Torchlight 2, I wanted to look at one of the mods I had subscribed to and I had no way of finding it. I've had to go through the Manage Your Game > Discussions to get to the right neighborhood. Can't there be a filter for looking through the workshops of all games, or at least a button that will let you quickly access your subscriptions? I suppose that the first thing may be more at the individual game level as Dungeon Defenders has filtering enabled, but if a game has workshop functionality shouldn't we be able to manage our subscriptions easily?
