Goldmine 9.2 on includes a button on the edit screens for both scheduled and completed activities that enables the user to see/edit the Notes for an activity in a larger, re-sizable window. You can use this feature when viewing history or entering info that will be in history.
This window has full editing capabilities, bold - italics - underline - spell check. So look for this button with two chevrons on it that expands into a full window for you.
My users really like this enhancement and are calling it the magic button. You are no longer constrained to scrolling in a tiny window in an activity for notes. For us, it is a far more important feature than the social media add-ons!
