As for me (a buyer):
I can only agree with the feedback. I dont even try buying anything for a few sales already, even though I really wanted to. usually I spend a couple hundred bucks on sales. But without any means to effectively browse through all the assets, I dont even feel like trying. And I know that I’m not alone with this…
The feature lacking most at sales is exclusive search, like excluding certain categories or tags from the results. With sales, I do not know what I am looking for, i’m just browsing for useful stuff, but I certainly know what I don’t need to see.
