I would love to hear people's thoughts so we can look to create something people want rather than just guessing...
I made very basic Panels for my own use (starting with the first public version of Configurator), mostly to trigger Scripts (most of them contained in the Panel with reference to some libraries), a few Filters and Selection-specific operations.
So the Containers for example were basically useless to me as I wanted all the buttons to be visible at all times.
What I would therefore like to see in a html5 successor to Configurator would be the ability to easily create buttons for menu items and to run Scripts from the Panels.
Thanks for chiming in in any case.
