Hi all,
I just installed the extension and used it to cycle between three windows (two side-by-side, taking up half the screen width each and one taking up almost the entire size of the screen on my 21" monitor). After a couple of switches, I actually felt queasy. And I don’t even have motion sensitivity (or at least never did before).
I don’t think motion is the way to handle focus indication.
It should be a static indicator that is also useful if you were to, for example, look away from your screen and back again after completing some other task.
Instead, how about adding a heavy shadow to the currently-focused window?
Also, I just noticed that the application name is gone from the top bar. This is a regression. The application name is an important landmark. It, combined with the active window indicator (whatever that ends up being) tells you where you are currently. What is the design problem that’s solved by removing it?
If I were making this decision, I would not include either of these changes. Instead, I would keep the current application landmark and make the current window indicator (the darker shadow) much more pronounced so that it is hard to miss.
