I was wondering if there is a windows resizing tool that remembers preferences and with one click launches the set of the application in their predefined space to start working without the hassle to reajust windows again.

I read about Divvy here but it seems do not propose that function yet.

Divvy
Divvy is an entirely new way of managing your workspace. It allows you to quickly and efficiently "divvy up" your screen into exact portions.

With Divvy, it’s as simple as a single click and drag in the Divvy interface and your window will be resized and moved to a relative portion of the screen. If that seems like too much work, you can go ahead and create as many different shortcuts as you'd like that resize and move your windows.

Pixo
Pixo was designed to act as an "Interface" between plugins and the user. Rather than traditional method of applying effects to an image, Pixo removes all the barriers and makes it a breeze to apply effects to an image anywhere you like.

What sets Pixo apart from other image effects applications is the way it applies the effects to images. You simply "Brush" the chosen effect on your image.

You can use Photoshop® compatible plugins† to enhance Pixo's power and create even more breath taking works of art from your existing digital images without the use of a single drop of colour
