A new version, 1.1.0, can now be downloaded. The main focus is fixing the annoyances found on mac os x and freebsd, while adding some nice functionalities, like status bar icon and "run as superuser". There are also some other small fixes and enhancements.
Since there is a lot of meat (I had to rewrite part of the rsync process controlling code), I decided to skip to 1.1 directly, instead of going for 1.0.1.
Let me know of any anomalies you will find, including behaviors which are different from the previous version.
