Besides the things already mentioned, I recommend: Afloat, http://infinite-labs.net/afloat/ http://infinite-labs.net/afloat/ -- keep single windows on top, make them translucent, make them pass clicks through. Flux, http://www.stereopsis.com/flux/ http://www.stereopsis.com/flux/ -- change color temperature with time of day. Cross-platform, wouldn't want to use a computer without it. Don't burn your retinas with blue bright light at 2am. Chromatic -- keep Chromium nightlies updated. GitX, http://gitx.frim.nl/ http://gitx.frim.nl/ -- Git browser / gui. Good for viewing history etc., like it more than Git Tower, also it's free. Skitch, http://skitch.com/ http://skitch.com/ -- quickly take and annotate screenshots, easily share them.
