In EE2 there was the "Server path to site's templates" for each site in MSM. So it was possible to have two separated folder structures similar to:
domain-A.tld (with whole ee system) /system /themes /css /js /templates domain-B.tld (without any system) /css /js /templates
So it was easy to run two different frontends.
Now in ee3 there is no possibility to set a custom basepath for the templates of different MSM-Sites. So all template files for both domains would now be stored in the directory of domain-A (when looking at the example above)
I'm working with the Editor 'Sublime Text' on a local machine and want to work on two complete different folder structures. How to do it with ee3?
