ExtraWM is a little Tool that improves the usability of Microsoft Windowstm, by adding two new methods for moving and resizing top-level windows (windows which reside at the desktop level of the user interface).
These two methods involves pressing a key on the keyboard (ALT) and a mouse button over any part of a window in order to move it or resize it. In short, by pressing ALT and...
Left mouse button - by dragging the mouse while the LMB is pressed, the window under the mouse is dragged as well (moved)
Middle mouse button - by dragging the mouse while MMB is pressed, the window under the mouse is resized from it's lower-right corner or from a corner or side, based on it's position (depends on the resizing mode - see the configuration file)
Since version 1.1 you can modify the keys and buttons using a simple configuration file, accessible from the program's start menu entry. Also since version 1.1 you can use three different resizing modes, which can choose different window sides and corners based on the Mouse Position - or just the simple version 1.0 resize mode which uses the bottom-right corner.
