Hello Garth,
That is correct. MyEclipse for Spring is currently focused on accelerating Spring Java development, providing some similar functionality that Grails provides to Groovy. It would be great to know what kind of features you would like to see added to MyEclipise for Spring, or possibly, a MyEclipse for Grails product that would accelerate Grails development. Or are you looking for Groovy support in MyEclipse for Spring, which is something we can provide educational materials about if the need is out there.
Let us know your thoughts,
Dave
