:Config:
Flamerobin v0.9.2.1851
Preferences -> Main Tree View -> Sort server entries alphabetically [checked]
:Problem:
Last added server is always on top of the main three (it is unsorted).
:Workaround:
Add "real" server, add a "fake" server (ex: "A"), close and reopen flamerobin.
not confirmed in 0.9.x in git
