Add the ability to go backwards during backtesting.

Hi all,

Do you think it would be possible to add the ability to go backwards during manual and automated backtesting so that it is possible to replay bars in order to better debug the code and in case of manual backtesting to better understand how the trade unfolded?

Would it be possible to also add hotkeys to control the back and forth? Like hotkeys to pause the backtesting, go back one bar, go forward one bar, go back X bars and go forward X bars.

It would be also good to be able to move back and forth while the backtesting is paused

Thanks in advance!
