Support offline storage for multiple recordings #125
Description
Currently recording a piece of media is limited to a single recording. You record something, play it again (possibly again), and when you're not happy, you start the whole process from the beginning.
It would be cool to use offline, local storage to temporarily store media files. So once you're happy, or discard the clip, it gets stored locally so it can be retrieved later.
See this blog post for considerations, and https://localforage.github.io/localForage/ for a good candidate to implement this feature.
Currently the total amount of storage on Chrome is <6% of free space and Firefox has a limit of <10% of free space.
