Income & Goal CRUD complete & list issues complete

I have gone thru the whole list for Income & Goals. I still have Savings & Expenditures to do, as well as the database edits. I plan on making the acheived_at category in goals table nullable as well as adjusting all monetary items to 2 decimal spaces. Since we are editing the DB, should we just go ahead and add a "notes" column and view for each table item? It would not be hard to implement. I can get html purifier wrapping the output easily.
