 - requesting the history of the current chat after reconnection
 - global availability (in drop down list) gets restored after reconnection
 - status icon in active chat changes when presence of the pen pal changes
-- infinite progress when open the dialogue with something that has no history to show
 
 ### Improvements
 - slightly reduced the traffic on the startup by not requesting history of all MUCs
-- completely rewritten message feed, now it works way faster
+
-- OPTIONAL RUNTIME dependency: "KIO Widgets" that is supposed to allow you to open a file in your default file manager
-- show in folder now is supposed to try it's best to show file in folder, even you don't have KIO installed
-- once uploaded local files don't get second time uploaded - the remote URL is reused
