How to add or remove sidebar?
Where are must search to add add new templete or edit modified templete (left and full).
This is strange to me. Why I must use templetes. Why concrete don't have option to add manually sidebar or remove sidebar :( on ui.
As for using templates, you are doing it on all your pages all the time. Plain Yogurt is a theme containing a few page types (templates), but it does seem like you are missing some.
Here is a package helping you to restore a lost core theme (in v. 5.5.0 to 5.6.0.2): http://www.concrete5.org/marketplace/addons/restore-core-themes/...
If you first follow the how-to below you will copy your existing theme to a new location and create a new theme out of it. Once that is done, installed and tested, you can go on with restoring the missing core files. After that, you can copy the newly restored page types ('full' and 'default') to your newly created theme and modify them to your liking.

On the page you wand to remove the sidebar from, hover over 'Edit' and click 'Design'. Choose the 'Full' page type.
