New code editor in the control panel
A new HTML-code editor was introduced into the control panel. It makes it easier to work with a page layout. For example, highlight the semantics, fold the blocks, and while holding the Ctrl button, view content blocks and go to the pages where they are edited.
Note that this editor is used in many popular software development environments. We also added a switch between the code editor (“Markup”) and the visual editor (“Design”) to the markup editing pages.
