0.8 users - I recommend opacity set between 30% and 50%.
The suggested contact list styles to match the popular message style "Big Icons
" (also shown). It includes both a bold contact bubbles layout, and a subtler group bubbles one.
Designed to be colourful, with clear on-line and off-line colours to attract attention, yet tasteful. Reminiscent of the Spotlight search results windows in Tiger, I think (maybe that's just me) - and the OS X traffic lights appear as the on- and off-line indicators. New message colour is the same as typing colour - when the message is ready, it begins to flash. Maybe not to everyone's taste, but I've been doing it that way for a while now :)
v2.0 now has colours to match all of the default Big Icons styles - blue, green, grey and red.
Includes two different list layouts, and four colour themes (the only difference is the group colour). Please note that I suggest you use these together, as the colours were chosen with translucent bubbles in mind, and they look a bit pants with any other layout :)
