The free one works.... You get a decent launcher for free. Only certain stuff is for the paid version but you can try it out on the free versionI want to stick with stock 5.0 for now. Was hoping there was a setting I'm missing that could reduce Icon sizes.
<Edit>
How much of a performance hit would Nova cause? Also, should I try the free version first or just buy the $4 option?
I detect no performance difference with my Nova Launcher Prime. To give you an idea of what you can do, here's my home screen and first page of my app drawer.
Any way to make the icons smaller?
