I would appreciate very much the possibility to create/activate "text bars". On numerous occasions, I need to take note of some events connected to a single session. I would be great to position the mouse over the January 30 bar and read "hei, here Mr Greenspan resigned from the Fed", or "this day saw a huge small trader partecipation", or "90% Up Volume session", and so on. The bar would be painted with different colors, and a text box would open simply on putting the mouse over them. Something like "Insert comment" function in Microsoft Excel.
