Ability to back-up all collections

[ghost]

Hello

It would be handy if there was an ability to bulk export all collections at once to a file format and import them again later. I understand the existing formats (HAR and Postman) may not support multiple collections in one file and you may prefer not to introduce an extra file format, but it would be handy even if it did nothing more than loop over all the collections and export a single file per collection.

The use case for this would be easily backing up and restoring your requests if you have many collections.

Thanks in advance
