How about a Company Tab which displays the Linked Company information in the Contact layout.
For most ACT! users I talk to, the major problems with Company records are:
1. They do not get created automatically when you create a Contact record, and
2. You have to keep flicking back and forth between Company and Contact records.
These two factors discourage people from using the Companies feature altogether. Can we not find a way to combine these two entities on one page?
I've previously floated the idea of a "windows" approach to ACT! where you could just arrange the information you wanted to see anywhere on the screen, kind of dashboard fashion. Maybe that was a step too far, but if we could have a Company Tab, you could fill in the address information there and it could be automatically copied to the Contact address fields as you go (just as the Salutation field works now).
There would normally be no need to have the address displayed twice on the screen so you could remove the Contact level address fields from the layout to free up screen space if you wished.
In Layout of the Company Tab could then be customized to show the information you need to see.
