Crawl space is the swiss army knife of app development. It is a free download made available by Adam Buchweitz of Crawl Space Games. The features list reads like a wish list for most developers: Timers, popups, background music control, table printing, paragraph control for text, help functionality, fade in and out, the list of features just goes on and on!
As I have begun to work with this great library, I really wonder why I didn’t adopt it much earlier (and save myself countless hours of development)!
