1. You can link to a note but it just seems like a second class feature - you need to share the note with yourself. Id like the ability to have off line only notebooks with links.

2. Thanks.

3. Per note encryption is useful, but it would be nicer to have the entire notebook stored off line on an encrypted disk. E.g. If I share my computer with people its easy to see what sets of files/notes are "open" by looking at Finders mounted disks list. If the data does not get transferred over the network it adds another layer of security - I do not have to rely on Apples implementation.

4. It is a limitation to me as reading/writing is the primary feature and its a personal preference to have a solid background. Same category as font size adjustment. Minor inconvenience.
