The cross-platform development environment LiveCode, perhaps the most successful of HyperCard’s successors, can deploy apps to Mac OS X, iOS, Windows, Android, and several flavors of Unix. LiveCode’s developer, RunRev, raised nearly $840,000 via Kickstarter in February 2013 to make an open source edition of LiveCode, and now the company is turning to the crowdfunding approach again. This time the goal is to enable LiveCode developers to write apps that can be deployed as HTML5 Web apps and run in a browser. It’s a compelling promise, but they’re just over halfway with three days to go, so check out the fundraising page (which isn’t run through Kickstarter) by the end of July if you’re interested in helping. follow link
Customize Open/Save Dialog Sidebars
You can customize the sidebar in an Open/Save dialog the same way you can in a Finder window: you can reorder the position of items, drag them off into puff-of-smoke oblivion, and even drag a folder from the dialog's list into the sidebar.
