It is possible to create a new Contact from the INBOX or e-mail view by hovering over contact names that are not in the system. A new Account cannot be created at the same time.
While it may be too cumbersome for a pop-up floating menu (new Contact) to create a secondary pop-up floating menu (new Account, like the "+" shown in the edit Contact view; it may be possible to add both at the same time. Therefore, I suggest:
- Adding a check box under the Account field of the new Contact floating menu, "[ ] Create Account"
- Adding a check box "[ ] + phone"
- Adding a check box "[ ] + address"
- Adding a check box "[ ] + web"
Item's 2-4 would copy over Contact fields to the Account record.
