Revived Ubiquity for Chrome
UbiChr is "Ubiquity for Chrome" - a revived command line interface that brings lots of useful command shortcuts.
In particular you can:
* open command like window (Ctrl+Space) execute commands with arguments and preview the results
* open new tabs and pass GET or POST parameters (Wikipedia search, dictionary lookup, translate text)
* fetch data via ajax, process it and display on extension popup preview (for example: IMDB movie lookup)
