- [ ] Support LESS for our skins [MediaWiki](https://gerrit.wikimedia.org/r/#/c/78669/)
- [ ] Create Documentation for the new jsonConfig and available options
- [ ] Make sure new player will work in standalone mode (without Kaltura) Another way to look at this is minimal amount of json to invoke a player without kaltura api requests.
