i tried a search to see if this mod already has a dedicated topic but i found nothing. just point me to it if my search was a fail a the mod already has one topic

I'm playing with this mod for about 10 days after finishing the game just once. i like many things that this mod brings to the game but other things are or bad or not necessary for me and i would like to keep the game more vanilla as possible.

The creator on Nexus wrote this
"If you only want certain features, or want everything except a couple changes, you can ask and I can point the way, but I'm not going to make a customized mod for every person. Some requests may just involve deleting some of the files, while others will involve editing specific lines (use Notepad++ so things are on separate lines.) It's not that hard to make edits if you just look at what Larian has done and follow the same structure for everything."

I tried to contact him but i had no reply,i know he's also here so maybe he can read here rather than on Nexus.
But i also hope there is someone else that can help me at least for just 1 of my requests.

So let's go to things i would like to modify
-The changes on the spells are the first thing and i'm working on it thanks to the help you are giving me on how to edit skilldata.txt
-i would like to remove all new active abilities just to keep the game cleaner but if it's not possibile i can just ignore them and don't use them. But if i can just have to delete some files i would like do it.
-i would like to remove "Class Focus" Rewards and to balance it,also remove the buffs to enemies ("Tactician NPCs have 15% more health, +1 Bodybuilding and Willpower, +3 initiative, and more movement speed so melee units are a bit more threatening.")
-remove the changes to Leadership

Then i would also like to know how could i translate the things this mod is adding (Italian). Using italian translation hides the new description of the modified talents. it's not important if i have a new item with english description but i want the sheet to be updated with the new changes brought by the mod.
