# TODO for Phase 2 (Editor)

- support massive maps
	- render to a bitmap and clip that in?
	- sometimes UI zooms in at once, then unzooms slowly. drop events?

- different UIs
	- 3D UI sharing the same structure as the 2D one
	- svg export some area, for manual mockups
	- web version
		- ggez, quicksilver, unrust could work

- easy UI bugs
	- big maps start centered over emptiness
	- deal with overlapping keys that still kinda happen (sim ctrl, escape game)
		- and missing keys, like no tooltip for turns, since they're only shown in editors now
	- bug: do need to recalculate current_selection whenever anything potentially changes camera, like follow

- traffic signal editor
	- button to reset intersection to original cycles
	- turns can belong to multiple cycles; the colors become slightly meaningless
	- support left turn yield

- stop sign editor
	- cant have no stop signs for two roads whose center line crosses
		- infer default policy

- be able to change road directions

- tests that edits + reload from scratch are equivalent

- undo support!
