I had lots of fun with a wood elf scout with mobile feat. We called him "The flash-y"
Now that it´s mentioned, there are also reactions that allow you to move in the enemy´s turn, like Rogue Scout´s 3rd lvl ability "Skirmisher" that allows you to move away (w/ provoking an AoO) after the enemy´s turn if it´s less than 5ft of you.

I do not know how you can do it if you do not have a pop-up to allow you to move after the enemy´s turn.
