Commands to:
Jump to locations
Do a free text search
Structured search
My todos
Open items

Ideas
Augment a page with data from another source
Use Firefox “Places” (history/marks)

Caveats
Frustrating developer experience
Error messages don’t have line numbers!
Security issues
Current release is 1.1
1.2 shortly
https://wiki.mozilla.org/Labs/Ubiquity/Ubiquity_0.1.2_Release_Notes_(Raging_Stream)
A bit ugly
To be determined:
Is a command line usable by my mom?

Happy Hacking
