I'm looking for a way to have list of all files/folders of the current directory in my terminal that updates automatically and runs while I'm actively navigating and editing files.  I imagine it to be somehow possible with a terminal multiplexer. But I don't know how you could notify another process about the change in the current process.  If I run watch ls -a in one split-view, it will only update when files in that same directory change, not when the directory of my other split-view changes.Basically, I want it to look somewhat like this:How could this be accomplished?
Showing list of files in current directory while navigating? (Screen, Linux)
linux;ls;gnu screen;watch;cwd
