I've used several launchers but there seems to be a halt developing them. For the most time, I used to use recently Neo Launcher, but it feels dated now, they are working on a rewrite and it's still beta (if not still alpha). Kvaesitso is a good launcher, but I'm too accustomed to the swipe up gesture to show apps and Kvaesitso just decided to make it upside down for me, and it feels odd even if you can change this to your preference. Finally, KISS launcher, which had halted development a bit but I find light and customizable enough. Not gonna lie here, as soon as Neo launcher gets to a stable state, I'm coming back.

Edit:

I wanted to mention a couple of killer features of KISS that you might probably like:

• Its dock can pin a couple of apps and have some spaces changing depending on the frequency of use.
• You can have a list of frequently used apps associated to a gesture (I use swipe-up and single-touch).
• If you are gonna use a not too frequently used app, you can have a gesture for this too (I use long-touch).
• Everything, and I mean EVERYTHING, is searchable. Well, not everything, but they surely allow you to search a lot of things.
