Now a function exists "Show sidebar on mobile " - Yes or No. Function works, but hiding Sidebar is not enough. Even when you choose No, browser mobile loading all content sidebar - with all the server requests and resource inquiries you have in the sidebar. This slows a lot of loading site over mobile.

Correct function is "Loads sidebar on mobile " - Yes or No. An administrator who wants to use a sidebar for a mobile, used Yes will load it, and whoever does not use sidebar, used  No - Will  stop loading a sidebar. This will accelerate with more than 8-10 points speed loading site mobile.

The trend towards mobile devices is growing every day and it will be very good if developers are considering this idea.
Thanks.
