JBLControl 0.4.2

Fixed

• Battery showed over 100% while charging (e.g. 138%). The speaker marks charging with the top bit of its battery value; JBLControl now reads the real level from it.

New

• 🔋⚡ Charging indicator. The battery icon in the panel fills to the real level, turns green with a bolt while charging, and red when low.
• Menu bar battery (Settings → General → Show battery percentage) now draws a battery with its level and a charging bolt, like the system battery.
• No low-battery alert while the speaker is plugged in.
