Exporting map as a pdf

Hi, I’ve been very impressed with Maphub so far.

I would like to see the ability to export the map to a pdf. Or failing that, export the map to a good quality image which could be printed poster-size, A0 or if not, then A1.

The maps that I’ve exported as an image so far seem to have a low resolution when zoomed out. Has anyone found how to create at a higher resolution? Or should I be exporting in a different available format nd using a third party software to print/convert or save?
