Remove back to top link about customizr

Yes I agree, it makes sense. This could be included in the next release !

I disagree! for whom who have usability issues it is an important piece of "text" the link at the bottom. A screen reader can not read the js arrow on the right side!

good point

I'm not usability expert, but I can't see any use case for back to top link, when you using screen reader.

[giorgioriccardi]

Screen reader was an example, but color blindness issues, Dyslexia and several other usability impediments can make some use of that text at the bottom. Nonetheless I see your point mejatysek,
I would suggest a new snippet to choose to remove or not the link "Back to the top" instead. How does that sound?

Let's make it optional, same as many other things. Just add another checkbox to theme settings. Snippets are nice, but be honest, who want's make childtheme only because of this?

since I didn't want to add another checkbox for that, a boolean filter has been added into the render method

if ( ! apply_filters('tc_show_text_btt', true) )
    return;

@mejatysek but I agree, nobody will create a child theme only for this ... :)
