Estimate/Quote - Add Note

I Would like the option to add a note for the quote/estimates. Purpose would be to record when I’ve chased customers up, to record feedback/changes, etc. All I need is Title, Detail, Date/time fields.

It could show on the History section under the Quote/Estimate the title. When clicked, either underneath the row, or a popup box, or some other page showing the date/time and details.
