I'd like to see a more intuitive navigation in map view. The current system that requires switching between different modes is rather cumbersome and cofuses end users.
Generally speaking, I suggest making it similar to Google maps. More specifically key functionality should be:

- Mouse wheel can be used to zoom in and out of the map. The screen moves proportionately to cursor position.
- Clicking on a node selects it
- Dragging the map is interpreted a panning
- Dragging with Shift pressed is interpreted as rectangular/lasso selection depending on settings. This behaviour can be seen in Bing maps
- If the map is in focus, arrows can be used to pan it
- There should be an option to show an overlay navigation menu. This should be set at the report creation stage.

The overlay should include zoom level, panning arrows, zoom to fit data and zoom to fit map buttons. Current Navigator isn't as easy to use, takes quite a lot of space and cannot be opened by default. (Earlier version Omnicope screenshots suggests that this was implemented before?)
- Hover graph should be shown regardless of other settings (currently it doesn't work in pan mode)

Note: I'm basing this on my experience in 2.7. I had a quick look in 2.8 and it seems to be still the same.
