The radar, lightning, visible satellite, IR satellite, and flight categories can be toggled on/off. Clicking on the map will start/stop the loop. Left-clicking on the "Speed" area will slow the loop and right-clicking will accelerate the loop, ranging from 0.1 to 5 second interval. Additional URL parameters include lt (center latitude), ln (center longitude), zm (zoom level, 0-12), nolabel (removes flight category icon ID labels), wide (thicken US state boundaries), and start (UTC start date/time, YYYYMMDDhhmm format, AWC data goes back up to 2 days, GLM data up to 5 hours). The URL should auto-update with the current settings, allowing for an easy bookmark/favorite.
