Hello everybody, good news for you.
The new version of Jfbchat (0.2.1) should be released the next weekend with some important improvements.
Jfbchat 0.2.1 will be more stable and faster due of many bugfixs and code improvement.
The problem with the collapse/uncollapse button was fixed, some contacts disappear after that this one was pressed.
Many other improvements were done on the graphical interface in order to make the usage more intuitive.
We recommend to update Jfbchat as soon as the application is released.
