Among the countless number of applications that just arrange windows on your desktop Flexiglass actually offers a convenient way to move, resize, maximize, and close windows on a Mac with a mouse, trackpad and keyboard.

* Move & Resize
Usually, when you want to move or resize a window on a Mac you are limited by its title bar or lower-right corner. Flexiglass enables more comfortable window management. To quickly move or resize the active window just place the mouse cursor over it, press a definable key and start dragging windows with the left or right mouse button respectively.

* Quick Layouts
If you used to work with more than one window at a time Flexiglass will help you to arrange windows on your screen any way you like. Just move a window to the right, left or top, and it will automatically resize and move itself to fill the half, quarter of the screen, or full screen.

* Quick Layout Shortcuts
User-defined shortcuts allow you to move windows to halves or quarters of the screen and back to original size. You can place a window in the center of the screen or move it from one monitor to another.

* Double-click to Zoom
Double-clicking on window title bar is the easiest way to expand it to full screen.

* Real Zoom & Real Close
You can change the default behavior of standard Mac OS X buttons. Right-clicking on the green Zoom button will maximize a window to full screen. Right-clicking on Close window button will quit the whole application.

* Multitouch Trackpad and Mouse
You can use finger gestures on your macbook trackpad or Magic trackpad to move and resize.
Flexiglass can save different settings for a trackpad and a mouse and automatically change them when you plug or unplug devices.

Customer Reviews

The best app I ever bought!

I have literally never taken the time to write up a review, but in this instance I feel very compelled to! Since switching from PC to apple I was struggling with the functionality of reorganizing my open windows, especially since I often have multiple documents / webpages open at a time. As soon as I downloaded flexiglass, those problems were history! It is incredibly intuitive to use, with very little required for the setup. Establishing keyboard shortcuts is fast and simple, and now my mac is far easier to maneuver than my former PC ever could be. Definitely recommend, $10 is nothing for this app!

Does not work in multiple user IMACs

Buy Sizeup instead. . Does the same thing but not limited to single users. I bought Flexiglass several years ago. Great functionality in single user mode. But if you have multiusers in one computer it crashes as soon as you switch users. I just bought Sizeup. Does the same thing but no longer limited. Too bad Flexiglass doesn’t keep up.
