I'd like to link to a audit of EncFS, the system that Safe is a wrapper for: https://defuse.ca/audits/encfs.htm

It highlights in my opinion a old and not rigorous implementation and design.

I'd not feel safe using it even if the developers of Safe did a great job choosing defaults.

It all depends on what you need. EncFS appears to be enough for what I need it for, encrypting files that I want to be a little more private than not at all on cloud storage. I personally wouldn't put sensitive information through it, but then again, I wouldn't put my sensitive information on a cloud provider either.

On top of that, what other per-file cross platform encryption options are there?

None, but consider that you can use Truecrypt over Dropbox. It's smart enough to upload only changed segments.

Unfortunately, any tiny edit within your TrueCrypt will cause Dropbox to re-read and re-hash the entire volume, and that can take a long time and drain a lot of battery. Safe fits more naturally with Dropbox.

Boxcryptor is an option, but it is not open source.

Boxcryptor 2 doesn't have a Linux client and Boxcryptor Classic was just mostly EncFS so its Linux support was the same as Safe here.
