Right now I'm using LauncherPro Plus, because it has the two options I'm looking for in a home launcher:
-Can reduce screens to 1
-Can hide apps in drawer

Is there any other launcher that has the same options, but is also more lightweight/simple? Or perhaps apps I can use for the default launcher to do the same? I'm using the Samsung Intercept, which isn't exactly the most powerful Android phone...and I don't know if SlideScreen fits the bill, but it froze both times I installed it and tried to change any settings.

Have you tried Zeam? Best for low memory phones(like spica)
