Enso : a real innovative (windows) software

Yeah, it’s not a Mac app’, but those guys could be from Apple for all I know... the concept is really cool !

The marketing pitch of the software :

Having to change programs to perform simple tasks—for example, making a quick calculation, or looking up a definition—breaks your concentration, takes you away from the task at hand, and wastes your valuable time. Enso lets you do common computing tasks easier and faster than ever before. You get a huge productivity boost and a simpler digital life.

You can do a lot of the same stuff with Quicksilver, I think. So do others:

Funny I have heard time and again about QuickSilver but never got down to testing it !
Thanks for the reminder

Edit : Just discovered a funny little app from the author of quicksilver called "Nocturne"

Nocturne is (yet another) simple app for switching a computer to night vision mode. It does, however, add a few things:

• Color correction in inverted and monochrome modes - you can correct hues when inverted and won’t lose a channel when using tinted monochrome.
• Window shadow toggling - if glowing windows aren’t your thing.
• Background removal - hide the desktop picture so you don’t see an inverted version.

I don’t know quicksilver or enso but for the keyboard enthusiasts out there try Launchy: http://launchy.net/ small, simple and very handy
