The fixes:

- Eliminated the show-tabs/hide-tabs button from the nav-bar

- sound improvements
Enhancement:  When the user clicks on the name of a sound on either a 
SoundTile or a SoundReadoutTile, a pop-up of available sounds is now 
presented, from whence the user can choose one.  This can be faster and 
more direct (and quieter!) than cycling through the available sounds one 
by one.

- Fixed a problem with loading a project containing projects
