Hi there Froog!
Very nice module! I have a case where I have only 2 fields in the Tab Content, Main. Besides that I've made all other tabs and fields invisible. Is it possible to make the tabs Content and Main invisible and to only show the two fields in the root? (something like you've done in a screenshot You've posted earlier: http://silverstripe.org/assets/Uploads/simplifyexample.png ).
I'd like to hear from you. Great work so far with this nice module!
Greetings, Allart
