Alternate sidebar icons made by TiberFCSL that the mod once used to come with.
Just unzip and drop the file into the mod to get the alternate icons by TiberFCSL.
They're pretty cool. Taken from cinematics and models. Maybe you prefer them. I am aware that I did not fully replace all of them. That is intentional as there are some that I like more than others.
His ecache10 should replace more but still not all, rename it to ecache09 before dropping it inside the mod if you plan to use that one.
