I would like to suggest new feature for developers, named Section Manager. I'll describe it's idea shortly.
Section Manager is DEBUG MODE only visible section under Configuration Tools. It contains list with all sections, at each section there's detailed information about section and also checkboxes (or dropdown) for section visibility management. So, using these controls user developer can show section, hide section or choose to display it only in DEBUG MODE or SUPER ADMIN mode.
Second main Section Manager's feature is section order management. Sections can be moved up and down, level up and level down using drag- n-drop and toolbar buttons.
Technically it all can be achieved in following way: Section Manager writes all modifications it made to Cache table (or other table). When section cache is rebuilt (using existing mechanism), after all Sections & SectionAdjustments keys are read from configs, Section Manager adjustments are applied. So result is stored in Sections Cache, where from platform reads section information.
It would attractive feature for In-Portal newbies and could be helpful specially during In-Portal-based project start phase.
