Best fics with Dimensional Manipulation powers

What are the best fics where the MC has powers revolved around manipulating parallel dimensions?

The only ones I've read are a two part snippet Pushing Back from Chunks of Worm where Taylor is a healer who can heal and even resurrect people by swapping them with a version of themselves from a parallel earth.

And more recently The Sum of All Taylors where a 12 year old Taylor triggers with the power to connect with parallel versions of herself borrowing their powers and memories. Most of the alt Taylors being from popular fanfics like Implacable and Sowing Doubt.
