[ADDENDUM]
You won't lose this customization upon skin upgrade. It is saved in your userdata/addon_data/skin.xonfluence folder in a file named settings.xml. Though in a very unsatisfactory way: not in any way organized, each modification is listed sequentially in the order you typed it in (this is Kodi standard).
If I were you I would peruse this settings.xml file immediately upon implementing the modifications, and paste out its last lines so that---
(1) you understand which code does what you want
and
(2) you can migrate your mods to a different skin if you so desire.
