Crimson Sticky

[Sickbrush]

I think it's a good motivating factor for a lot of people. I tend to be sliiiiiightly against things like a thumbnail roll in the header but temporary stickies, that's cool!
I think you can make another criteria at the top in the sketchbooks category, between Important threads and Normal threads and move them there while they're being "awarded".
Are you also thinking about adding a badge like the daggers ?
Either way, my vote is go for it
