A place to stick enhancements to Form Mode Manager that are too half-baked to hope to get into the main module itself.
Features
Currently FMM Extras offers one proof of concept:
Provides a field formatter to add a button-style link to add edit the contents of that field in a Form Mode Manager tab you have created that shows only that field or a few related fields.
Presently everything is hard-coded but if this would be useful to you it'll be worth us making it configurable!
