Hi, just my two cents...
I find it confusing that there's an element type called "Group" on the Palette, when there is also the construct of Group elsewhere in the app for grouping elements together.
The double usage of the name also makes it ambiguous when I post to this forum regarding Groups not exporting to PDF, or if you were to ask me to "select all the Groups".
I do find the element-type itself very useful, using it a lot on the web where it's sometimes called a "fieldset".
Thanks for listening.
