Would love to have more contact filtering options. These could include some of the following (and more)
  1. Filter by total spend (which would pull from Payment activity). This could be helpful for people wanting to target loyal customers / donors. There is a workaround but it should be native.
  2. Filter by length since last contact (and would allow more advanced filtration by channel, inbound/outbound, etc.) again workarounds can be created but should be native.
  3. Filter by opportunities (number, stage, etc.)
  4. Filter by forms completed
