I'm too lazy to read all these long posts, but what does moving the autobattle to ImprovedGameplay change, other than the fact that you need to click a couple of times to enable it?

Moving the autobattle to ImprovedGameplay means that it can only be used against an opponent with the same version of the mod. That is, in a game against ideological opponents, and those who are simply too lazy to install/update the mod, you will have to do without quick battles or put up with the fact that a quick battle, like an angel vs. butterflies, consumes mana.

in quick battles, after all the dragonflies bite the hydra at the beginning, they STOP MOVING!!! the hydra stands there and unpunished kills the dragonflies standing around it!!!!!!!!
I will work on a fix...

This is a well-known fact; AlexSpl wrote about it here. The opportunity to use it in the game is not often available, and it can be perceived as a feature, like the towers.
