There are several requests scattered about regarding the new custom fields for contact/company. They are all related to simply making them "first class" objects in the system, the same as the canned fields. FD should learn from history as this area trips up all the major CRM vendors (and it's not really that hard..)
Custom fields should be able to:
- be used as placeholders
- Trigger events
- Be available in canned responses
- Act as filters
- Accessed from API
- Import/export
- etc
