Okay, better than nothing, I guess, but I really do consider searching separate from browsing.
This is the same as the issue with the Windows 8 "start menu" that heavily impaired usability when having a lot of installed applications. The Windows 8 start menu displayed all installed applications in a flat view, instead of folders. There too, there was a search/filter functionality but that means you have to know the exact name of what you're looking for ahead of time, rather than browsing a specific category.
I'm really happy that you will implement the fast search functionality, but again, I see it as an entirely different feature that solves a different problem.
