Cross-hairs

[pauldbnut]

A little wish, big effort? But asking anyway...

Hovering the mouse over spectrum or waterfall displays a vertical "tuning bar" with centre and bandwidth limits plus channelised tuned frequency.

An optional mode could be cross-hairs. Vertical to show "exact" frequency. Horizontal to show dB if in the spectrum pane, time in the waterfall.

That last would also be invaluable (especially during paused data file playback) for spotting and recording synchronised events at different band positions, e.g. interference components.
