I had an idea for a campaign I would GM for some of my friends. It wouldn't be a DFRPG game so don't worry about the laws but I would use Fate for the system and a few of my friends mentioned that they would like to have some of these powers, but I have some problems in making the powers. And there are people here who are very good at making custom powers and abilities so I thought to ask for some help.

Here are the powers:
1. Psychomancy says you can supercharge your brain and thus improve your reaction time and make yourself think faster. So, how would you model this stat wise? It could be just placing an aspect of some kind on yourself but I would like if someone can think of a similar power that gives you some mechanical benefits.
2. A power that enables the user to see a few seconds into the future and thus allowing him to anticipate his opponents moves.
3. A power that enables the user to subtly pull on time in a bubble around them, stretching it and making time pass more slowly around them. This would enable the user to slow down time and get a few moments to prepare himself while his opponents are "slowed" down. I was thinking this could be just a form of Inhuman Speed, slowing everything around him.
4. A power similar to slowing down time, but one that enables the user to push on time in a bubble around him, compressing it and making it pass more quickly around him.
Thanks in advance for any ideas you might have!
