Simply amazing

For me, this is a must. I mostly use keyboard cutsom actions and they are awesome. You can set any keyboard (mouse accessible as well) shortcut to either move a window, resize it, align it, go back to previous settings, etc. While highly customizable and powerfull, its simple to configure and use.
I tried few others and this one looks to be the best and has a reasonnable price tag. I highly recommend it.
