Hi, I'm Oshane Bailey, a final year Computer Science at the University of the West Indies, for GSOC 2017, I'm aiming to take on the task of improving the theme editor by making it more like an IDE. @pigeonflight suggested an improvement plan for the theme editor on Products.CMFPlone issue tracker page, which I will be using as the base plan. Improving the experience for the theme editor while giving it more super powers, to me, it is of great value to a lot of plone developers, designers and myself.
I'm currently looking at Codegen, C9, ACE editor and other IDEs, which offers lightweight high-performance IDE. If there's any suggestion of any improvements you would like to see.
