I've bounced off that blog post in the past, because it makes it appear the first step to doing something in avy is to position all my files and "windows" (a "window" is an editing pane inside Emacs) in some clever way, and after I got all that setup, and the windows are all looking at just the right parts of the files, then I can move a paragraph from one window to another with just a few special keystrokes.

I feel like moving from a large monitor to a small monitor would limit the usefulness of avy; it's weird that the physical size of a monitor would limit a tool like this.

If I can only see 3 lines of text at a time (maybe an accessibility thing), the usefulness of Vim-bindings is not significantly reduced. Is the same true for avy?

Again, I'm willing to learn that I was wrong, but this is the specific issue that ended my enthusiasm for learning avy.
