Today I fixed the map canvas to 1200 x 1200 px so the numbers stay in place at reloads. With a fixed size, centered image, and square shape, I should be able to allow for rescaling to other sizes and still keep the numbers in the right rooms.
But perhaps more importantly, I added my whole collection of maps to a menu so there is an easy access collection of maps to populate. If other map makers want some or all of their maps to be added, I'll expand the menu.
Fixed Wandering monsters and relationships note in DunMap. Went with a simpler generation of a bigger set of WMs at the beginning and adding relationships to the bottom of the note as rooms are added. This might split up the relations above and below hand entered notes, but that should not be too much of a problem, since most nodes will be added at the beginning.
Added font size and color adjustments to the Style dialog.
Added a button to lock out addition of nodes by stray clicks.
