In Sonar Viewer, I find myself using the scales on the right of sonar windows to estimate the depth of objects of interest. I may then type that depth as part of a waypoint name.

Sonar Viewer uses the current mouse cursor position to update a coordinate display in the upper right corner of the screen. Could you also show bottom depth for this position and the current depth (at cursor position)? That takes some of the guess work out of my estimations.

As a second request, could the Waypoint creation dialog include depth? If so, could that depth value be pre-filled based on current cursor position at time-of-right-click? The user could click on the object, the bottom (or anywhere in the water column for that matter) to trigger the pre-filled value.
