This looks cool. I am a bit off topic here. But my only fear is this entices some people to make it the default in terminals over time.

Like all moderne UIs now have animations, ranging from very slow to barely fast enough for my personal perception.

And it becomes increasingly hard to disable those animations. They creep up absolutely everywhere. And they drive me crazy. I want my computer to act instantaneously. Redraw within 8ms.

Almost all animations are also impossible to abort or skip. Worse plenty will animate concurrently. So you might be jumping around on a webpage faster than the animation, which then jumps you back to then slowly animate.

My life on this planet is finite. A computer isstupidly fast. Why waste my precious lifetime? How many minute of life do developers of animations steal from people?

I do understand that I process visual stimulus faster than most people. Making me an outlier. Modern interfaces are devoided of identifiable buttons and all look like a smear of emptiness with a few dollops of text and burger icons to interact with. Making it hard to notice what changed between two actions. Maybe increasing the need for animations to help people follow

In any case, I suffer greatly with animations.

On Mac, I recently mistakenly held Shift (or some other key combo?), before hitting Space to open QuickLook as I was gonna select a few image files. It proceeded to open quicklook with an incredibly slow >5s animation, very annoying :S
