Funny enough that's precisely my use case for tiling window managers. I'm often referencing one app to do work in another, and often one is just a bit too overlapped to see what I need, and I also need to lay windows out every time I do this work. With a tiling window manager, you can be sure that your app is not obfuscated, and there are various adjustments you can make to pane size and layout to get the right amount of screen space and positioning for apps. You can also save and restore layouts for particulars workflows.
