[TYPO3-dev] edit mm tables in backend forms with TCA

I hope I understood everything correctly. I was also in a need of 
something like this. To store attributes that are attached to a certain 
relation between 2 data entries of 2 tables. And this can be n:n as 
well. So ... the non-typo way to do this is to just have a table storing 
the 2 (u)id's plus all the additional fields that are necessary for 
"describing" this relation.

So ... maybe there should be an MM-Plus-Attributes option (in the 
kickstarter) that automatically creates a sheet (or a palette) on which 
you have a select option for the foreign uid plus all the fields that 
are part of the MM-table. You get this sheet in the edit mode of both 
records that are related of cause.

Furthermore a "create new relation" button would be needed that extends 
the sheet / palette by another fieldset. Alternatively always one set 
more than relations found in the MM table could be rendered extending 
itself after storing data.

I really think there could be a broader need and use of that.

Jochen
