One of the benefits of ACT is to have a lot of resources available for immediate access. In my sales organization we have so many different product and marketing offerings that it is almost impossible to keep track of them.
Here's my suggestion:
1. Contact layout - here we could create text fields that would allow pasting content. At the very lest, let the text field that allow more than one line of text to be included, i.e. carriage returns and tabs.
2. Allow the use of hyperlinks that could go to somewhere on the internet or on the hdd for information on whatever the subject is.
3. Provide a side knowledge base that could be clicked while still keeping the detailed contact screen active. I'm thinking like the side links to companies, groups, etc. but the active contact screen would also remain displayed.
