When I have a lot of audio files in different directories, it's annoying to have to use Audio.DIRECTORY_FILE_NAME way to reference them. I wish I could say that a bunch of files should be in their own object that I could use elsewhere. Like justTheAudioINeed = Audio.speech.male, with way shorter individual names for each variable.
The development server doesn't have a favicon and 404s when trying to serve linked icons. This means you have to export your app before you can verify that the icons look as expected.
It would be great if the development server would serve these.
