Edit 2: they made it a pain in the ass to change your password apparently now they favor only 20 characters max (rip my 35 character password).
That just screams they're not storing passwords properly. If you're salt+hashing your passwords, they could throw Hamlet into the password field and the only limit is how big the text entry field can be. The output is a fixed length string, so I put length should be immaterial.
IIRC, the windows version of this is a setting where you can hit CTRL and it makes a moderately large circle that contracts towards the pointer. It's been in since at least W7/Vista, possibly XP. I've used it on and off for years (especially with 3 27" monitors) because of how easy it is to lose the cursor.
