v1.2.1

Added

• Auto-reconnect — an optional toggle that automatically retries the last
  device after an unexpected drop, before the disconnect alarm. Shown only
  where it can actually work (not for Bluetooth in a mobile browser).
• Nicer packet sound — a pleasant bell whose pitch still tracks signal
  strength, plus a new "disconnect only" sound mode. The disconnect alarm now
  sounds on every unexpected drop.

Changed

• Location now starts automatically when you connect (Android) — no need to
  tap the 3D map's "Enable location" button anymore.
• Steadier location on the 3D map — occasional GPS jumps (sudden ~200 m
  hops) are filtered out.
• 3D map zooms in to street level even on large maps, and deep zoom is
  smoother.
• 3D camera framing — "Center on me" no longer jerks at the end of its move,
  and repeaters are framed with a little headroom above them.

Fixed

• 2D charts could stop updating with Display set to All, until you switched
  the Display window and back.
• Help (?) tooltips could appear away from their icon.
• Seen Repeaters now shows the true last RSSI/SNR, not a rounded/averaged value.
• Received Packets always lists every repeater as a column, not only the ones on
  the current page.
• 3D map selection no longer clears itself on its own.
• 3D map tiles no longer flicker while panning or zooming.
• Footer text now has proper contrast in light mode.
