dahov, see our developers' replies to your questions below.

1. Anyway the transferring information is encrypted with encryption
algorithms and is never transmitted without encryption. In new version the
encryption with SSL is still supported.
2. These are temporary disadvantages which will be fixed in
release version.
3. This functionality is not available currently but it is planned for
next releases.
4. All files are uploaded in pages having the size of 4Kb. There are no
limitations on file size. Mail files are uploaded fully.
5. In first release only text files can be reviewed. The processing of
other files types will be added in next versions. There will be no need to
add the desktop identifier manually- it will be uploaded automatically using
the synchronization mechanism.
The automatic network settings feature is added. The stability of mail
processing and sending is significantly improved.
