In T162790 we created an ugly but editable version of editing the grammatical features of a Form. We now want it to make it pretty. It should have a similar look to statements. (But it should not have references, qualifiers and ranks. The property part of the statement is not an existing property and not linked but instead hard-coded text.
Mockup: {F6843804}
Acceptance criteria:
* The grammatical feature part of a form seamlessly integrates with its statements.
* I can view and edit existing grammatical forms.
* I can add new grammatical features.
Open question:
* Do we need a selector for novalue/somevalue?
* Does the order of grammatical statements matter? Or: should grammatical features be stored and displayed in the order they're entered? Or in any other particular order?
