It may be helpful to know that @grb is not a bitwarden employee. He is just a customer like you and I. Bitwarden has granted him and me forum admin privs, but neither of us has access to any non-published information.
Much of what you ask already has on-going conversations. You might find answers or workarounds in them. I do see value (as @grb suggests) in keeping the conversations self-contained.
- Allow export of a specific folder/collection
- Inheritance of Access Permissions for Nested Collections
- Drag and Drop vault items/entries/folders/collections
- Progress bar during downloading - Bitwarden Send
- Automated Vault Export / Backup to cloud storage
Overall, though, the theme of your questions seems to center around “why don’t Bitwarden development priorities align with my needs?”. For that, I do not see an existing topic, so you may need to create a new topic to discuss that.
