MondoMouse is a mouse enhancement that gives added capabilities to your mouse.

Features:

Move windows quickly
Just point at the window and drag it where you want it. Your mouse pointer can be anywhere over the window-- no need to click window's title bar.

Resize windows in place
Make it just the right size without switching applications. Just point and resize, instantly.
MondoMouse can also resize windows from any corner, not just the lower-right corner. Resizing happens from whichever corner is closest to the mouse pointer.

Focus Follows Mouse
Let the mouse pointer hover over a window, and it comes to the front automatically.

But wait, there's more!
Ever have trouble finding a window? MondoMouse identifies the window under the mouse for you via a floating text box (as seen in the screenshots above). Find just the right window from the dozens that may be open, immediately!
