SoundTree Recorder 0.10.28

- Added a quick recording button to the Library section so that a recording can be initiated directly from Topic-contexts - Fixed an issue where volume buttons didn't work during playback over Bluetooth headphones. - Fixed the Input Source button on the Record tab showing a stale device after it was disconnected (e.g. unplugging a USB microphone) - The Input Source picker now shows previously selected devices that are no longer connected, greyed out, instead of just dropping them from the list
