LEE123  Why isn't everyone using this? This is some good old save you tons of time and wrist action software. This stuff is standard fare on linux but this is the first I have used it on the macbook pro. I love it. Focus follows mouse people rejoice. The default value for "Focus follows mouse" is way to high. Set this setting to 0.30 or so and see how easy it is to switch windows.  
(Version 1.4.2)

MDOGNRDOG  One feature I really miss when not using the GNOME desktop is the nifty little feature where ALT+click anywhere on a window is the same as clicking on the title bar of that window -- you can drag the window by grabbing anywhere.

Particularly on a laptop, this is a nice addition.

Mondomouse gives you this feature, but at a cost. Its key bindings do not always interact with the standard key bindings in the ideal fashion, for one thing.

The other, which is why I probably won't buy it, is that it's kind of a hog. Watching my GeekTool top output shows some pretty serious memory usage, and I saw an immediately noticeable bite out of my battery life on my 17" MacBook Pro when I had it running. So the ability to sling windows around my desktop more easily with the touchpad comes with the fact that I can do so for approximately 8% less time before having to plug back in.

THORNIST  I used MondoMouse for a while, then tried something else for a while but decided to return to it. Unfortunately I'd lost my license key and the email that contained it. I've tried several times (quoting my order reference which I do still have) to get the license resent to me using the contact form on the developers' website, but have heard nothing back. Shoddy service - probablty best to avoid the company.  
(Version 1.4.3)

ROBOTANK  This latest beta is having a curious side effect for me. When MondoMouse is active, TextEdit repeatedly opens, over and over again. I can quit it or force quit it or whatever, and it will relaunch again within a few seconds. Deactivating MondoMouse causes the problem to cease. Snow Leopard 10.6.1, Intel Core 2 Duo.  
(Version 1.4.4b1)

SHERMAN WILCOX  Nope, not working for me. Stops after a couple of uses (running demo) under Snow Leopard.  
(Version 1.4.4b1)

DANA SUTTON  Fine, I'm glad we now have a version that stops the suddenly quitting problem. But note that after the upgrade has been installed the preference panel still identifies itself as v. 1.4.3.  
(Version 1.4.4b1)

EASER  Version 1.4.3 loads fine on my machine. With the loss of WindowShade, I've found it really annoying to have to switch from one open window to another. For what I do (grading), I need to have several documents open simultaneously. Windowshading let me instantly see information (e.g, an outline) in a document below while I was writing comments in a grade sheet from another program.

I had not used MondoMouse in a long time, but I now find that the focus follows mouse feature is becoming indispensable. This program is worth it to me for that feature alone.  
(Version 1.4.3)

DANA SUTTON  Something wrong with the installer. Double click, it opens the v.1.4.2 preference without installing the update.  
(Version 1.4.3)

MARUKO DRINKING TEAM  This is the most important Mac enhancement for lots of us.

Especially when combined with a decent mouse driver that lets you assign a couple of the extra buttons on your mouse to the MondoMouse shortcut keys. That way, you have dedicated window resize and move buttons, which work at any point in any window in any app, even if the window is in the background.

This awesome little tool dramatically enhances the way you interact with every single application on your Mac, every day.   
(Version 1.4.3)

TOMIS  In case anyone doesn't know:

Try clicking on a background window while holding down the command key. You'll find that you can move, resize, even use controls in the background window without even bringing it to the front.

Obviously MondoMouse does much more than this, but that basic functionality is built in to the OS.
