hopefully this question wasn't asked too often - in that case, I'm sorry that I didn't find it.
I created Zen-Subthemes and if a (minor) update for Zen is available and done sometimes my design for the subtheme gets changed - not always in a way I want it.
So, what is the best way to keep the design of the subtheme?
Is it a best-practice to prevent the subtheme from updating?
If yes, how can I achieve that?
Thanks for your patience and your help.
