Can someone give me a use case of where terminal shaders are providing functionality, rather than eye candy? I mean I love my retro crt look, but there has to be a better reason to have shaders on a term

I use a cursor following shader. It is subtle, but i feel like it draws your eye to where ever the input cursor lands. I train users on a tui application, and it seems to help them as well.

It looks cool, and it is accessibility as well as it helps me find the cursor.

People with not perfect eyesight might benefit more from it too.
