Last week Marc Palmer announced his Grails Documentation Widget. To bad it was an OS X Dashboard Widget so I couldn't use it on my Windows based machine. Marc already suggested to buy a decent OS... Maybe my boss is reading this someday and buys me an Apple ;-)
When the widget was released I was playing a little bit with Adobe AIR and I decided to port the widget to - or better, create something similar in - Adobe AIR.
It gives you the power to do an incremental search on dynamic methods, tags, scripts etc.
Have a look at http://www.grails.org/Peek+in+Grails for more info and download instructions.
