Force keeping app window on top - Mac OS X

问题

Earlier i used Afloat for this but now it seems to be dead...

Is there any alive software or any simple "handy" way to force keeping app window on top over others (including fullscreen apps)

I can imagine this can be done with adding something to plist files inside .app like

<!-- Info.plist -->

<key>LSUIElement</key>
<true /> 

for showing app over any fullscreen app (with keystroke)

Google didn't help me much (

Set the level of your mainWindow as

[_window setLevel:NSModalPanelWindowLevel];
