+ Started rewriting my map editor from the ground up as a web app
+ Object placement with live green dot preview (press A, then click)
+ Object selection (click) and deletion (press X)
+ Object renaming (select, then use the inspector on the right)
+ Object movement (select, press G, click in the new location)
+ Hyperspace route creation/removal (select source, shift-click destination)
+ Planet/station resizing (press R, move the mouse, click to stop)
+ Scrolling (press S, move the mouse, click to stop or press S to reset)
+ Save map data to a local file (click the filing cabinet icon)
+ Load existing data (drag a file into the browser window)
- Drag-and-drop breaks the entire page in some browsers
- Dynamic SVG resizing is broken in some browsers and it looks weird
