cax just asked this question in Wuala:

Wuala's wish list (from a Mac user)

- A non UI client for Mac. I don't see the need of having UI integrated to the FS. Why not two separate apps? or even better UI client on Web. 
- spotlight integrated?? 
- A cocoa based client (UI only) 
- An API for developers 
-Why the mounted dir is called localhost? why not use the machine's name? 
- WualaFS as a service. NO UI, just start and stop (mount, umount) 
- WebDAV support.

add by bagelcat:
- a shortcut for "show comments"
