This new UI makes me cringe, all its done is make it so you need to do another step to get to absolutely everything, and its an annoying step considering pop up menus never really work to well.
Think a good change would be the ability to sell prestiege upgrades back, because at the moment, getting particles is neigh impossible after a certain point so it isn't possible to really get the amount of the even more expensive upgrade if you also spent some in wrong places.
The new capacitor is completly broken, utterly and totally useless. Even if it did dump directly into the reactor like people ask, it will still likely blow up any setup that is end game, and any other part of the game. Even if it doesn't, the amount of heat it generates makes it so the extra autosell is useless and you make actually less power than before. This needs some massive balancing.
Be nice if the capacitor prestiege upgrade effected starting heat and power so that reactor wouldn't blow up in a few ticks for such small amount of power.
Thanks for the feedback :) The UI is now fixed with all menus visible !!
