Trying to remove "Important" folder, Gmail --> Mail
I've been trying to remove my "Important" folder that Gmail automatically sets up, but none of the tutorials I've been able to find are any help. They all say to disable the "show in IMAP" option in the Label settings in Gmail, but I don't have such an option. I have "Show" and "Hide," and "Hide" is selected. Yet it still shows up in my Mail. It's not the end of the world; it just takes up space and I never use it because the emails that automatically get put in it are pretty randomly selected and usually not the actually important ones. Can anybody suggest another way for me to get rid of this folder? Thanks!
