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.

Rock star app!


If you do any type of writing, reading, or work with any type of documents or applications where you need to compare multiple versions simultaneously and need a way to quickly resize the application window or document windows — Flexiglass is your app. Apple has JUST created the side-by-side view in El Capitan — boring — because you don’t always view side-by-side. Flexiglass has been doing split views for years and with a few key strokes you ALSO get TOP & BOTTOM split as well as a way to QUARTER split the apps/windwos into the four corners of your screen display. This is such a rock star app — I love it. You’ll love it too!

Buggy & Expensive

Matt Hiaz

I bought Flexiglass to allow for a very convenient way to move and resize windows. It implements the functionality very poorly. First, moving doesn't work on all types of windows, e.g., System Preferences. Second, resizing Terminal and similar text-based applications also selects text while resizing. How hard is it to do one thing and then do it right?!

After getting in touch with the support, the only thing they mentioned is "we hope to fix it in the future". Very unsatsifying. This is by no means a $10 app, given the buggy implementation.

Two birds with one stone


I've used Zooom/2 for years and Cinch for about a year. The former I used for adjusting window size, similar to the way Flexiglass does it. And I used Cinch for dragging windows to the top of the screen to maximize.

After purchasing Flexiglass, I was able to uninstall both of those apps and say goodbye. Zooom/2 never seems to be updated, so it's comforting knowing that I'm using software that is actively developed and supported. It's also odd having an application/menubar icon that only does one thing (Cinch).

The only thing I might miss is that, with Cinch (it looks like another reviewer below had the same comment), when I drag a window to the top of the screen, it maximizes, but if I drag it away from the top, it goes back to its original size. Sometimes this is nice to be able to do. With Flexiglass and its Quick Layout drag option, it lets me drag the window around after dragging it to the top, but it stays maximized (rather than going back to the original size before I dragged it to the top), so if I want the window smaller (which I probably do if I'm dragging it around), I have to do that manually. Minor nitpitck, but maybe the developers could add a checkbox preference that, when checked, would remember window sizes after using the Quick Layout drag option. Sometimes, however, I might want the window to stay maximized. Not as often as I'd want it to go back to the original size, but sometimes, I think...
