I think, that a lot of partners would appreciate some marketpalece improvements.
1. Marketplace looks very old and has poor promotion from your side.
2. Full text search missing. I alway have problem to find particular thing.
3. Filtering by vendor would be nice.
4. Kentico version like 4.0 are obsolete. No one would be loking for it.

A view of Downloads, or votes, or something to indicate 'this is being used by people' would be really helpful, especially as a Marketplace web part developer who has no view other than comments, as to whether my controls are actually being used.
Beside of the filter by a vendor and full-text search option, are there other improvements you have in mind?
