leafo said something on the lines that the search features are worked on. But no specifics. There was this overhaul a short while ago. But I would think that any changes would be done to the actual search button.
The stuff discussed in threads is usually about the browse features and this is tags and filtering or lack of filtering.
I do hope they improve the recommendation features. But I suspect this is difficult, as their algorithm would have to evalute games better. And since tags are dev chosen, they lack accuracy. Also, only 11 tags. Steam has 20 tags that are user chosen. That's a ton more accuracy to work with for recommendations by tags.
Oh, and don't spoil your browsing experience too much. It is just so easy to hide a lot of games with this. I added all the basic functions to the tool, including togging it "off". I really should rework the description of the tools. Should you try it and have an idea for a screenshot that shows what it can do, let me know. The other two tools were easy.
