Some small details ;
1— The Maximum number of characters mouseover label show “65” for the maximum recommended when it’s 160-165
2— In fronted, I will really like to see the maximum of characters set in the admin as a starting point and going with the number of characters left each time something is typed in the input.
I think it will be more user-friendly that way…
1 - This is the number of characters for the page title (Title Tag), it should not be longer than 65 characters. Some SEO experts even suggest a number between 50 and 60. See also here: moz.com/learn/seo/title-tag
2 - Okay, you would like to have a countdown instead of a countup? I think that it really makes sense here. I will set it on the wish list for the next stable release (maybe today or in the next days).
