Hello Armin,
Thank you for your post.
We never publish a detailed roadmap. But the most pressing priorities we are currently working on are as follows:
- Updated and improved authorization system based on TLS 1.2 (this will replace the current RSA+AES).
- 2-factor authentication for the Hosts and later for the self-hosted server as well
- Viewer for MacOSX (and possibly Linux)
- Updated and improved mobile version with a full-fledged address book.
These are just some of the things we are planning for the nearest future. There are also numerous fixes and little features that we are going to include with each update.
