Since Minion is logged in to an account (somewhere ). It would be REALLY nice if it could synchronize add-ons (adding/removing as needed) across multiple computers (I use it on 2 desktop PCs and a laptop sometimes too).
Data files would be nice too, but I realize that's MUCH harder (merge conflicts, etc etc).
In the meantime, I have something like that set up using Skydrive. Dropbox or anything other similar application would work too. Simply put, I moved the Addons folder out of the "My Documents\Elder Scrolls Online\live" folder to my Skydrive folder, and then from a command prompt used the mklink command to create a junction or link.
So the Addon folder in My documents is redirected to the addon folder on my skydrive. Do that on both computers and you'll stay perfectly synchronised.
If you want to set this up and need further info just let me know.
