Sync Database Schema & Collection Schema
To efficiently work in a development environment and then apply changes to the database changes, something like diff between development (source) and production (target) database, there has to be a feature of synchronising Schema only (without data) with optional opt in for Data as well. It should be bi directional. While synchronising Collections, Schema validation should also be allowed to synchronise apart from indexes. All these options should be allowed to select or de select with proper warnings.
