i messed up with 1.55.02 and the about box was disabled; it was fixed soon after with v 1.55.03.
old fashioned folder nodes:
if you create a COMMAND node (not folder contents), but instead of specifying a command, specify a folder.
(you can hold control key and click on folder button to browse for folder),
it will more properly choose name, hint, icon for the folder,
and now will open that folder when you click on that button.
the purpose here is when you want to have a button to open a folder using your normal file explorer.
