Robo's istrolid script, which adds the ability to see the status of reloading turrets.

ReloadDisplayScript.js

/*
Script that displays the reload of turrets. Sometimes may have not critical bugs.
Press H button to start displaying the reload of selected units. You can change that hotkey in the settings.
You should load this script after the others, else it may not work, because other scripts can overwrite changes it making.
Made by RoboDrone @riemnand.
