we have in topview a few more navigattion elements as in sideview
e.g. zoom, home

There is no need to abstain those in sideview

Practically, this requires quite some changes on both the frontend and the server. The OWS protocol addition of MSS does not really support this feature of zomming into sideviews.

This is a very sensible feature request, but I do not see this in 1.8.0.

I see only changes on the frontend in mpl_qtwidget. I don't see changes on serverside, because by the options entries we also can scale.

For requesting an image based on zooming we don’t need to change the server.

To solve this get_lat_lon can be used to find the closest index of the waypoint table of the zoom window by self.ax.figure.canvas.ax.viewLim.x0 and self.ax.figure.canvas.ax.viewLim.x1. As the waypoints of the flightpath are enumerated an index slice of both best indices can be formed to request from the server the new image.

An impementation has to persist on inserting, deleting or moving a waypoint. Only by the home selection the old initial setup has to be loaded.
