It would be very helpful to be able to view all activity history for an account on one screen. Right now it's very difficult to get a good picture of true activity history when emails are being logged on a separate screen. It's great they filter our to the contact they're associated with, but it would be great to see a single, chronological history for an entire account.
It would be great to be able to result completed calls using a dropdown. I've created a custom field for call results, but the only one that populates the activity history on the account screen is a text field. A dropdown would be far more efficient.
When completing an activity and choosing "save & new" it would be great if the contact and account were automatically filled in with the same one the current activity is being completed for. It takes a lot of time to go search them out everytime you complete one activity and wish to create a follow-up for the exact same contact.
