There come a time when every developer finds new, improved ways of doing things. I'm no exception to this, and when I learn something new, I try to implement it wherever I may find it beneficial.
Because of the way I was hacking together CRM controls for the JGE, I required these external sources to load before proceeding to implement the controls. Most users of the JGE experienced this requirement by way of a load time that was either very long, or didn't work at all! That said, I had been on the lookout for a better method of synchronously loading these scripts without using the dreaded eval() statement.
If you found that the JGE hadn't worked properly for you in the past, I encourage you to grab the latest release.
