Nope, better to shift to a site that plays the role of google translate rather than google docs + translate.
No need to overcomplicate + requires a lot more work to persist data, manage user data (i.e. pw)
Also, it's questionable whether or not translators even use google docs? Because a lot of the styling should be done in the wordpress editor directly anyways
Preferably with draft.js as a base.
So that this project can serve as kinda like a google docs alternative for document translators.
