Videos on Phabricator
Current limitations: only videos under 4mb can be uploaded; no fallback support for video types (if a webm video is uploaded and the user is using Safari, there will be an empty box in lieu of the video); no inline playback for mp4/movs

To work around this and to ensure cross-browser compatibility, I typically convert the video into an animated gif using ffmpeg and gifsicle using this command: ffmpeg -i input.mov -pix_fmt rgb24 -r 10 -f gif - | gifsicle --optimize=3 > output.gif

Saving preferences via JS
During local development, it might be useful to go through a flow several times. For flows that are only shown to the user for a limited number of times, user preferences are used to track the state that should be presented to the user. This can be cleared via running  from the browser console.
