The large map resizes and works well for keeping up all the time for navigation. However it does have that large box with the zone names and with infomap is quite cluttered. The minimap is a fine alternative, but you can't open and close the minimap with the letter "M" like you can with the full map. Or can you?
Open the User.ini file in your vanguard/bin directory with notepad or the text editor of your choice and scroll down to the end of the aliases. For me this was alias 114, but you should use the first empty one. Put the following after the first free alias:
(Command="/togglewindow minimap",Alias="Minimap")Then scroll down to the first empty binding setting. For me this was 108. Put
(Key=77,Ctrl=False,Alt=False,Shift=True,Command="OpenMap")This will make the key for opening the minimap SHIFT-M, but I went into the regular in game settings for controls and swapped those between mini and regular map.
Save and you're all set.
On a somewhat unrelated note, the ability to look around without moving your toon by holding the left mouse button seems to get lost periodically. The relevant binding that gets lost is
(Key=1,Ctrl=False,Alt=False,Shift=False,Command="MouseLook")
