Many similar types of apps (real app or via web display) allow users to select custom values for display when clicking on a feature or location.
Curently, for example, when the WIND is displayed, True Wind Bearing & Speed are displayed. When the PRESSURE mode is active, only Pressure is displayed.
At ALL TIMES and in all display modes (wind, pressure, temp, etc) it would be very useful to display the WGS84 coordinates (in user-customisable format - eg, (D)DD MM SS.ss, (D)DD M.MMM, etc). At minimum users should have the option to display this as one of their default settings, as well as choose other displayable attributes (depending on the mode).
For example, I would like to see the WIND (brg & speed) as well as PRESSURE, plus COORDINATE all at once!

The Lat/Long grid does not show actual Lat/Long labels - at least on the default version accessed via the web.
It would be helpful if they did so I don't have to rely on general knowledge of an approximate coordinate or counting grids to figure out what the coordinate is!
Additionally, on the default web version the grid doesn't scale according to the view zoom factor.
However, on both the custom Vendée Globe and Lisa Blair versions, the grids do show both the Lat & Long labels and do scale (from say 20° to 10° to 5° steps).
This is the kind of functionality required in the default web version.
