QuickBuds 4.10.0

Both apps

• Noise control with both buds out of ear: the app says "Put an earbud in to change noise control" and shows the real mode. On the phone this is a toast. On the PC it is a 3 s hint in place of the mode buttons.
• Smart noise cancelling shows the level the buds chose, for example "ANC S·M".
• Equalizer: quick preset clicks no longer lag or jump back. The buds end on the last pick.
• Report a problem: Send stays off until there is a description. The report includes the app's warnings.
• Hide old battery levels: the row has a battery icon.

Android

• Dev tools: switching to Detailed no longer stalls. The live log keeps updating after days of logging.

Desktop (Windows and Linux)

• Motion, as on the phone: the selection slides in the mode buttons, the preset bar and the theme list. Buttons sink on press. The connection state fades. A theme change crossfades.
• Switches slide again.

Earbuds

• Confirmed by owners: realme Buds Air7 Pro and OPPO Enco Buds2.
• The README covers Android, Windows and Linux.

Thanks to @MilyuKom0dek for the reports (#8, #9).
