Remove current app from background

[mlg321]

I have background remover that I've set I double tap the status bar to remove ALL apps in the app switcher. I used to have a tweak that would allow me to quit the current app I'm in and remove just that app from the task switcher. I can't seem to find it. I have app "App quit current" but that just seems to quit the app, not remove it from the task switcher. Any body know of it?
