I agree. I've tried many different launchers and always come back to Nova. The customization is great, and it just seems more smooth and stable than all of the other launchers I've tried.
Don't really care for it. All my devices until my N5 had 4 screens. The GEL on my N5 I couldn't get used to having Now on the left, and needing to have an icon on every page I wanted to have.
Came down to I wanted control over my home screens.
I just downloaded/installed it but it's not working...every time I try to set it as my home launcher it says Google Search has stopped and returns to my Nova homescreen...
