- HD imagery is available for the 1974-78 aerial photos. On other eras the HD button is dimmed and explains why when tapped. - The era dial now checks the actual imagery to see whether photos exist for that era. - Fixed the split slider being hard to grab at the edges and jumping to a wrong position. - Fixed dialogs overlapping the ad at the bottom, which could hide their buttons. - Fixed several cases where the app could close unexpectedly, including right after launch.
