The Image-Line forum has some decent reference on how to do the custom scripts, but I haven’t found much in the way of custom scripts that people are sharing on that forum, nor much discussion on the topic.

Also, the preset scripts don’t take advantage of all of the available system commands in an efficient manner. The preset scripts are pretty useful, but in my experience with them I’m not real keen on continually flipping pages on the launchpad, nor am I that keen about the fader control on the Launchpad. However, I’m using the Launchpad to minimize my mouse activity in the program, and I really like it in terms of workflow. I like to use the APC40 for launching clips having used it with Ableton for a while, so I keep the APC40 doing that same task in the “Performance Mode” of FL Studio 11. This new version of FL Studio has some preset scripts for the APC40 and Launchpad, and the ability to create your own. I’ve been experimenting with the use of the APC40 and Launchpad in controlling the recently released FL Studio 11.
