Since there's a few nice suggestions from the 1.7.10 repo that didn't make it over here, here is a collection of the ones I could find:
Automatic Linking of power sources with nearby blocks on placement
-Configuration of world decoration spawn rates (already implemented in 1.7.10, was added a little after Edwin's original split)
-Component for telekinesis on non-item entities.
-Gravity Well to affect flight
-Increase Fire resistance from affinities
-Redstone pulse component
-Cross-dimensional recall talent
-Spells imbued on armour
-(Similarly) Battlemage armour to have built-in protective spells
-Scatter spell shape, fires multiple weaker projectiles in a cone
