Undo button

I was somewhat to quick in deleting all of the data I put in for over six months at my 1 minute chart. This was on smarttrader. Appearantly there is no 'undo button' at the moment. Result: over six months of data gone.... It would be nice if that as a feature could be added. Another thing; Is it possible to create the possibillity to enter the possibillity to get a random chart out of the past 'in view' ? At the moment the only thing you can do is scroll back. Not really a possibillity if you would like to look at a chart on a 1 minutechart of 1 or 2 years back in time...... It would be nice if the possibillity is there to have a chart 'on-call' .
