I strongly dislike ingame teleporting and pause menu quick travel. I'd much rather the game have more ways for me to get to where I'm going than simply materializing wherever I want to be.

Let the travel itself be part of the game instead of just a way to link the "real" parts of the game together. Make it fun and fast to move around, add unlockable shortcuts, add more in-universe traveling options. Let me get to where I'm going myself instead of doing it for me, and make it fun to do so.

Especially in open world games, not only is this the most true, but they're the worst offenders. Literally what is the point of making an open world and then letting people skip it? You see everything once and that's it. If you make an open world full of opportunities to wander and explore, and then players want to avoid it as much as possible via teleportation, you have failed as a designer.
