I really like a lot about Fleksy. It has never been able to stick and supplant SwiftKey as my defualt keyboard, though. I've given it a try numeropus times. I just don't care for the way I have to change predicted words, etc. in Fleksy (but I never swipe on any keyboard, so that is probably a big factor).
The Fleksy keyboard, in my opinion, has *the* best layout of any, though. It's just like a BlackBerry keyboard (the second alpha row is flush to the sides of the screen). I've requested that layout from SwiftKey as a theme option. Given all their themes have the same layout, I'm not holding my breath.. The actual typing I've done on Fleksy is noticably faster because of the layout (it's the other stuff that slows down the process pkus the other features I miss).
I haven't missed another keyboard with this type layout have I?
