Linting for missing dependencies
Christos, it would be good to set up some linting that would point out missing dependencies, e.g.: https://gitlab.coko.foundation/wax/wax-prosemirror/blob/master/wax-prosemirror-services/src/TrackChangeService/TrackChangeService.js#L2
If a package is depending on another package, that must be listed in the package's package.json, otherwise you end up with missing dependencies as soon as you take an editor out of the monorepo (as I did).
