There are some problems with tray icon based interface.

• as described here qnapi icon appears in wrong place if unity desktop environment (ubuntu) is used #17, tray-based GUIs do not work well in Unity environments unless is compiled against Qt 5.5
• many users reported that after launching qnapi nothing happens - they probably expect a window to appear, but only small icon were added to a system tray, which could be easily unnoticed

I wonder on a real change here. The most promising and obvious alternative is a main window, with all options available from standard application menus and drag&drop area, where you can drop file/directory to begin subtitle downloading (or directory scanning).

Wouldn't it be easier for an ordinary user? Or both interfaces should be supported and the choice left to user (via settings)?
What do you think about this idea?
