Creating thumbnails for user presets

When animation presets were first introduced there was a system available so you could create your own thumbnails but it was cumbersome and a little crazy to use. The functionality was dropped. Your only option is to use scripting and create your own interface.

I have over 200 animation presets for 2D and 3D motion that rely on in and out points of layers to control motion. I created an alias in my standard user presets folder that points to dropbox so I can get to these from any computer at any time and they always stay updated. I keep track of them by careful file naming and sub folders. That's the easiest way to do it for me. Maybe, one day, I'll take all of those presets and write a script that turns the whole thing into something that I can sell, but for now, a descriptive file name and a decent folder structure is all that is required for me to find exactly what I want in a couple of seconds.
