## Description
By re organising the panels in the IDE, we are creating a new Code
Editor only panel which is separate from the main / canvas and the
explorer panel. This ensures that the Code Editor is not remounted when
switching between Split screen and Full screen. This PR is also
improving the Preview mode by not changing urls when entering and
exiting preview modes.
