This version includes the latest changes which are considered too experimental to be featured in the base work-in-progress branch. As such, it should only be used for testing purposes.

• last waves of code refactoring/cleanup and complexity reduction (focus on Scrutinizer hot spots)
• editor system refactoring :
  • separate responsibilities into different models, introduce callbacks
  • implement custom columns editability
  • implement order address columns editability
  • implement inventory columns editability
  • create a spreadsheet summarizing the compatibility of each editor across the different Magento versions (use three different states : "untested", "tested and functional", "tested with problems" - provide links to the related issues -)
  • start filling up the compatibility spreadsheet
• JS code refactoring :
  • remove CDATA sections
  • refactor and optimize code when possible
  • review the code style (follow some best practices)
  • write comments (use JSDoc) (probably not worth the time)
  • implement an object manager, to remove as much clutter as possible from the global scope, and automatically cleanup unneeded/overridable objects (especially for Ajax grids)
• move the columns list form to dedicated window, as for the other forms (avoid cluttering any external wrapping form with a lot of parameters)
• rework the profiles bar so that the number of displayed profiles is adapted to the available width
• rework the "Access All" profiles permission (make all the profiles be available from everywhere, except in the bar)
• rework the sales items columns (implement the advanced text filter, improve their extensibility, and allow to display a customizable value when exported) (later)
