Thanks! All of this stuff is coming in some form in the near future.
As a side-note, there is "unofficial" offline access right now. All of your edits are batched up when you edit offline and will be synced with the server when you reconnect. You just can't close your browser window/tab until you reconnect.
The undelete bar thing is already fixed and will be pushed out soon.
Key points for keeping it relevant:
- Mobile
- Offline access
- Export/print
Small nitpick: Deleting an empty item shouldn't bring up the undo delete bar.
