For a client project, we needed the ability to create custom layouts for the add and edit paths for field collections (e.g. /field-collection/[fieldname]/[nid]/edit)
The attached patch adds in support for various ctools and page_manager plugins to make this happen. I've only done preliminary testing of it so far but it does appear to work. We'll be testing it more intensively over the coming days and weeks, so if there are any improvements to be made, I'll post them back here.
