Yeah. I don't know if it affects what people coming to your profile views, but when you go to your dashboard on a deskop/laptop, the star indicates which comic is your "primary." (Their terminology is "main" series. Same difference XD)
It's not a big deal, but when I click on "Episodes" to update a DH page, it auto takes me to my other comic. It's such a minor annoyance, I'm too lazy to actually do anything about it XD I'm not on the app anyway, so eh? I think my comics are still listed in alphabetical order when a person views my profile, so DH will be the first one they see.
