• hideable menus, place context menus better, remove top menu bar, add a simple OSD
• loading screens reflect what's printed to the terminal
• depict pedestrians and bikes with more detail
• tool to scroll through an agent's route
• make simulation speed controls actually work

0.1.4

• improve stop sign editor UI (toggle entire roads)
• better mouseover / selection rendering
• better traffic signal rendering (show time left, use outlines for yields)
• make cars actually stop and briefly wait at stop signs
• improve edit mode diff visualization (cross-hatching)
• render actual stop signs, not just red lines
• fix intersection policies confused by conflicting straight turns with lane-changing
• fix mac scrolling
• better turn indicators
• nicer unzoomed view of roads, with different colors for big/small roads

0.1.5

(release file size jumped from ~15MB to ~70MB because of new PSRC trips)

• improve UX of intersection editors
• define a better set of maps included by default
• improve drawing speed by batching more stuff
• better default traffic signal policies for many cases
• import and visualize census data
• fix missing sidewalks on downtown one-ways
• import and visualize PSRC trip data

0.1.6

• slider widget for controlling time and speed
• fixing bad polyline geometry in most cases; visualizing routes should no longer be buggy
• handle PSRC trips that begin or end out-of-bounds
• draw agents in unzoomed mode in a way simpler way
• improve edit mode: detect reverts to original, easier lane type switching
• lots of fixes for buses: handle edits better, read sequence of stops correctly from GTFS
• set up A/B tests faster

0.1.7

• bulk and revert tools in edit mode
• improve turns and default intersection policies when bike/bus lanes involved
• new tool to manually hint for short roads and weird intersections. some problems have now been manually fixed
• scoreboard of trip results for sandbox and A/B test mode
• reduce lag when sim is running at full speeds, but system is too slow
• switch to easbar's contraction hierarchy crate, making all pathfinding INSANELY fast
• remove weird rules about the world freezing when traffic signals are in "overtime"

0.1.8

• edit mode: convert to a ped scramble cycle, simplify stop sign editor by removing individual turns
• ui: put labels next to sliders, organize modal menus into sections, add a minimize/maximize icon
• A/B test mode: savestate, include time controls and agent following/route tools here
• use more OSM data for turn lanes, turn restrictions from lanes, turn restrictions between entire roads
• dont attempt to cross a traffic signal if there's absolutely no hope
• improve bus route UI tools and make routes using transit more sane
• user-defined shortcuts for jumping between views of a map
