  Caching
    I do not see this module as being very cache-friendly. There will have to be some thinking when it comes to this.
   
  - Block cache: lags on select boxes on anonymous/registered users
  - Caching modes 'normal': interrupts scheme changing for anonymous users. works OK w/ logged in ones
