I'm using VisuStella's Input Combo Skills plugin and it works fine, but the only issue is that the window for the combo skills has a gradually fading opacity that clashes with the limited palette of my game, which I try to keep to 4 colors as much as possible. Because of the terms of use, I cannot edit the plugin or parameters (which would be difficult anyway since the js is obfuscated lol). I am aware this is an incredibly niche issue.
The plugin in question.
So, the only compromise I can think of is to use a separate script that effects window opacity or is able to remove specific windows, since that would loophole the strict restrictions around the plugin. I know the name of the window created is Window_ComboSkillList. If there's some script that can mess with individual window opacity (and maybe also position...) I would love to try it. I've already tried just biting the bullet and using a palette plugin to force everything to stay in 4 colors, but it makes the game kind of unplayable since I bent the rules a bit in order to make things more comfortable for player's eyes.
