Zoom level

[plusdespam]

Hello, oxuxmaps is the best  8-) tool I have ever used. Thank you for your work. I have 2 questions:

- With very high resolutions screens I find that autoswitch from one map to the next could be improved with a possiblity of a x800 or more Zoom factor instead of a max of x500% as in current version.

- With barometer set as default height messurement, do the total positive or negative cumulatives use these barometric altitudes or do they use the standard gps altitude values (also does the gpx export uses barometer mesures) ?
