Yep, and that script does work. I actually use it, but with a few nests for each account… account #1 all sues amarr skin and are combat oriented, all of account 2 uses plasma, they’re my eyes and trade alts, account 3 is the red one, they’re all sabres/logoff traps. Each has its own overview/general screen looks. I use with EvE-O Preview, and between that and different screens for different account/usage it helps keep track of what i’m doing.
With my setup, I just have to make the change on 3 ‘mains’ and then run the script and all my alts are taken care of.
(Also - protip) Back up your configs on your own (and often). Google drive is an awesome thing 
aaaaand plug: DOWN WITH POSes!!! DIE DIE DIE.
and yet another plug: CCPLZ fix structure/corp to use PURE ACLs with NESTED perms and FFS seperate things to be granular [edit removed wall of text]
