This is a great list, but two of my favorites that are missing:

Divvy - http://mizage.com/divvy/

DragonDrop - http://shinyplasticbag.com/dragondrop/

Also, Slate is extremely flexible: https://github.com/jigish/slate/blob/master/README.md

OSS alternative to Divvy: ShiftIt https://github.com/fikovnik/ShiftIt

Thanks!

Tried out DragonDrop - it's pretty awesome and instantly solves a problem I never realised I had!

Each time I use DragonDrop I'm met with "Wait, what did you just do!?" It solves such an interesting problem - it's a must have.

Does Divvy let you tile windows with margins between windows or the edge of the screen?
