* Card generation (extended card)

VISUALIZATION

*	arrange a "shift" of the viewport to select a layer
-	and restriction on movement
+	each viewport has its own layer

LOGICS

dungeon:
	unavailability:
*		flood
*		landscape change
*		building
*			houses
*			trees
*			water
*			factories
*			bridges
*			tunnels
*			airports
*		roads at the intersection of layers
?	generator
?	rivers, cities
*	edges (independent lifting, void)

activity restriction
synchronization of landscape changes

GUI

-	construction of a two-level station in all directions
-	construction of a worm-hole from one layer to a neighbour layer
**	work with the station (construction, removal / blocking of parts / cost)
*	menu template for management / construction

+	add selection of number of layers
+	only show layer switches for available layers
?	only show tiles of current layer
+	fix the coordinates in the "help area"
-	fix the coordinates in the start screen
-	signatures, station names (on all layers), effects (on the desired layer)

BAGI
+	station deletion (departure)
*	Expansion of the underground station does not work (when adding cells, a new one is added)
-	GF. "jumps" (the non-editable part of the station changes randomly when the station is modified)
