When Kget is started it's shown in tray system but the main interface is hidden.
It seems kget will remember its last state before quitting. If window was open when kget quits (Ctrl+Q) it will restore the window when started.

That's why if the window is hidden in tray system and then it's closed from there it will appear hidden in next start, it seems not intuitive at all.
There should be an option to "Start kget minimized to tray", otherwise kget window should be shown when kget is started, no mattering its last state before being closed.
