Advanced data matrix - FieldFrame maybe?

Hi.

I have a little challenge on a current project:

I need some kind of field input, where my cp-users can input an unlimited number of rows into some kind of data matrix. Basicly what Brandon Kelly’s Field Frame offers…

But i need to be able to input different types of rows, so that the users will be able to build a different structure for every entry…

I have build this function with the FieldFrame ext., using FF select to choose type for each row, and then use {if Type=="xxx"} for output in my templates, and it works - but theres a lot of fields to overview in the cp, and its not really that user friendly back-end-wise. So i need my backend to behave, according to type-selection:

If user selects type1 - only show fields for use in type 1 and so on

Does that make any sense? I guess im looking for an extended FieldFrame.

extension-recommendations or solutions are welcome 😊
