Yea the sub-menu is kinda annoying to have to click, but I never use it. Just a nice look, but was more referring to just an option to the sync folder that doesn't exist in the menu from the current version.
I'm sure it's been suggested, but I think adding a gui like the new updated dropbox application would be nice. Expecially the option to open the parent folder BTSync from the menubar icon. Thanks for the amazing app!
