First Lion screenshot.
Haven't customised too much, only a spot of geektool, bowtie and icon changes. Going to wait for things like themepark to be fully compatible. My CandyBar is having a fit so a few are default at the moment (Chrome) and my drive icons wont change. Dock is smaller than usual as I use Alfred as it's a lot faster. Changed the linen mission control (I had to) and the dashboard background - but not the iCal yet (SAVE MY EYES)
Started using spaces a lot more with the magic mouse gestures
Space One - Browsing, Twitter and note taking
Space Two - iTunes, Spotify and email (Sparrow)
Space Three - Reeder, Instapaper (fluid created), iCal, Things
Space Four - (Only open when editing) Aperture, Final Cut, Pixelmator, Adobe CS5, Coda
