Kvaesitso takes a little to get used to. It is not like a traditional launcher and is no where near as customizable as Nova but I still really like it.
If you don't like having a ton of icons, only use a limited number of widgets, you like to use a search bar, and you don't like shoving things in the app screen in to folders, I suggest giving it a try.
The home screen only allows one row of icons. You have a set of icons as your favorites in the app screen. You can use tags, rather than folders, to organize icons.
It is different but it is very polished.
Open sourcing Nova would be a huge game changer. Hopefully the original creator can find something in legal where he can release it himself. I am sure a lot of devs would love to help him clean it up ready for open sourcing.
