Feature requests - improved charting

[chrfle]

Being able to compare multiple recordings is a nice feature. I know you can manually align these by adjusting the offset but it would be even better if you could just drag them relative to each other on the chart window.

With the release of 2.3.0 software today this has been improved. You can make a selection, right-click on a recording and choose to offset it by the selection.
