• Update bitrate handling in restore broken record and set bitrate based on format capabilities.
• Refactor recording format information display to use multiple HTML resources for each format instead of a combined one.
• Refactor the recording sample rate information display to use multiple HTML resources for each sample rate instead of a combined one.
• Refactor the recording bitrate information display to use multiple HTML resources for each bitrate instead of a combined one.
• Enable vertical scrolling for dialog text in AppComponents
• Added a dialog with a recommendation to switch to the new app V2.
