That's a very valid question. The short answer is, that was not my first choice/anything close to a good solution but more of a hack. The longer answer follows below. I am building a new application - let's call it A (an X11 app) that needs to use an existing X11 application (that I can't change) - let's call it B. I would launch A and occasionally have to to fire up B to do some stuff related to what A does/is doing. Ideally, I would like B to be a sub-tab or somehow be 'contained within' A - to avoid the two showing up as two disconnected applications on the desktop and keep the two within the same 'container'. For lack of better options, I decided to make Xephyr my container and use i3 to display A and then B and switch back-n-forth etc. I'm open to any suggestions on better ways of achieving this. Thanks.
