Not to keep pushing this software, but SizeUp allows for a keyboard shortcut to do full size windows (for any window) and then snap back to previous size, plus a whole mess of other great features. Its literally the app that kept me using OS X after switching from Linux. And its name your own price licensing.

That looks like a great piece of software! I have been bugged by the lack of maximize for a while now. This looks like it will fit the bill nicely.

Out of curiosity, what is a typical "donation" to the developer in this style of licensing?

He wrote a blog post (which I think was submitted here) that details the first week or two of sales. http://www.irradiatedsoftware.com/blog/files/a_week_of_sizeu...

He asks for $2.99 min so his paypal fees are payed, etc. I gave a bit more and got a personal thank you. It does have a demo mode as well.

The posts from the people that are releasing the sales data are extremely interesting to me. Thanks!

As an aside, does anyone know of an agregator of blog posts concerning sales data for ISV's?

Some developer blogs might show graphs so you can see the trend of their sales, usually with a line showing where they finally become a viable business, but few release hard numbers. I'm happy to share more hard numbers if anyone asks, since I feel this is very valuable data for anyone considering ISV or the "name your price" model.

Firefox and iTunes are the broken ones. Most other apps handle the zoom button correctly -- they resize the window to be just big enough to fit the contents.

Terminal.app - if there was one app that I wished would resize itself to handle the widest possible line, that is it. Alas, it just zooms to fill the entire screen - which is somewhat comedic at 10 pt Courier on a 2560x1600 30" Monitor whose longest line in the scrollback-buffer is 75 characters.

Yeah, I hate the inability to maximize windows. In addition, I wish "paste plain text" had consistent keyboard commands across applications.

You can make the keyboard commands consistent in the Keyboard pane of System Preferences. I find it best to do it per-application as the menu item title isn't always the same, e.g. "Paste and Match Style" in Apple applications, "Paste With Current Style" in some others.

Full screen Cocoa apps, it's a hack but it works. http://ianhenderson.org/megazoomer.html
