I'm currently using LauncherPro which lets me have 4x5 icons and a bar at the bottom of my home screen. Are there any alternative Launcher apps that will let me cram more in?
Not a launcher app itself, but MultIcon (review link) lets you cram multiple icons into a teeny tiny space. Also available via cyrket.
Now, that unconfigured screnshot is the extreme example -- but the density ranges from 4 incons in the space of 1 on down. It's pretty handy -- plus it comes with its own shortcuts widgets to a few things. Can't have icons for normal folders, however. Bummer.
Zeam (Zeam.org) is a great alternative launcher that offers an 8x8 workspace on each screen (up to 7) as well as multiple dock icons.

You should try the ADW.launcher , its free and lets you have up to a 8 x 8 screen plus 4 dock icons . It also allows you to resize widgets ( I reduce my clock to 1x1 and increase a few others).
Don't forget you can use folders as well to cram lots of apps into one space, I usually keep apps in category folders, it's a nice way of being organised also!
