I just installed this theme and think it will work well as a starting point (yes, I always use a child theme), except for a few quirks with the mobile menu.
1. There is a link in the dropdown menu called "Navigation" which takes you to the home page. Why on earth is this here? And how can I remove it?
(I see that some people have asked this before and didn't get answers, but the links to their websites show they got it solved.)
2. Depending on the browser, an arrow will appear over the little blue menu lines. Is there any way for that not to happen?
I can't share my client's site, but both issues happen on just a regular install so go to http://wordpress.org/themes/attitude and make the window mobile size to see both issues.
