I like the new class properties that are available in LabVIEW 2011:
Currently I have to create a Virtual Class folder and insert the VIs with a specific layout. It would be nice if we could create those directly from the GOOP context menu. Just like LabVIEW can with Non-GOOP classes.
I agree, the problem is that the current release has to work in 2010 as well.
We're releasing GDS 4.5 any day now, and after that we can drop 2010 support, and therefor add the Property node support. So in the next release this will be available. If you want to become a beta tester, you get access to this feature soon.
