Spotify Volume Controls Goosey

I am not a very experience BTT user.

Is there a way to do this:

I want to drag and drop a file from my Downloads Folder into an App called Flume.

So now I have to move downloads to the right side of the screen and Flume to the left side of the screen so now I can see both and drag from one window to the other.

I'd love to do this with one button or gesture.

Sorry.
Is your question asking how you can quickly snap a window to the right/left of your screen? Or are you wanting to, with a click of a button, move a file from you downloads folder into Flume?

I just want to move the windows but each window is from a different program.

Also I use Path Finder in place of Appleā€™s Finder so it would be nice if BTT recognized that.

The Spotify controls are a bit goosey for the volume settings. Lagging and jumping around wildly.

ok. sorry but I can't help you with that. you might want @Andreas_Hegenberg to help.
thanks
