What's New in Map Calipers

MapCalipers 1.10 What's New Game borders in transit feeds • Transit feeds can now include a game border. When you import a feed that has one, MapCalipers asks whether to use it as your game region. • A feed's detail page now has a Game Region section. It shows a mini-map of the border and your stops, and how many stops fall inside it. • From there, tap Set Active Region to start playing in that region, or Edit to adjust the border first. • Feeds with a border show a small map icon in the Transit Feeds list. • The polygon region editor has a new Load from Feed menu, so you can start from a feed's border. • During first-time setup, picking a feed that has a border fills in your play area for you. Clearer route highlighting • Highlighting a route now hides every other line, stop and label, so the route you picked stands out. • The highlighted route stays visible at any zoom level. • Tap the route's label again to clear the highlight. Closing Inspect or switching tools also clears it. Fixes • Route and stop filters: turning off "All Enabled" and then switching on a single route no longer re-enables every route. You can now play with just a few routes enabled. Stops had the same bug, and it's fixed too. • Zooming and panning no longer bring back hidden routes while one route is highlighted.
