******* Works great on OS X 10.7 Lion *******
Essentials app can easily become your favorite and irreplaceable shortcuts pad. Just press hotkey (default is Ctrl + space, but you can customize it in preferences) and Essentials will appear where ever your mouse cursor is (or not, if you choose so in preferences).
You can use it to:
- quickly launch applications
- access assorted folders, documents and files of any kind
- act as clipboard or "dropbox" for your e-mail messages, text clippings, PDF and image clippings
- drag/drop paths and images (from for ex. Adobe Illustrator)
- create, drag/drop or/and mix color item from standard OS X palette
- make YOUR OWN simple Terminal commands/scripts (that can act as droplets too! :) ...now which app can do that! :D)
- run all items from a selected group

Customize it!
- resize groups by holding Command key (⌘) and scroll up or down (or pinch it on trackpad)
