Looks similar to obsidian’s sliding panes

To this day I’m still surprised there aren’t any Smooth Caret Animation packages for Emacs

I did this in my personal keybindings, in which one mode is visit mode. Once you get into it by hitting v, you can shrink, enlarge, swap and select window.

bdw as emacs is a gui app are there other any animations aspects in emacs or any package that add some animation bling to emacs

You can definitely drag emacs window borders smoothly

What’s going on on the gif doesn’t look particularly smooth, so as long as the horizontal steps are limited to multiples of the character width, this should be easy to write in Emacs Lisp (5-10 lines).

But doing something practical with it will require extra work. I.e. the depicted process is probably a part of some specific buffer management/switching mechanism, and that would require some extra analysis to replicate and integrate.
