@mguichard , this would be even better if the options would be:
Add option to control whether thebe-rocket shows up
Add option to force automatic execution of thebe-rocket with an indication of loading untill the entire output is shown. In this way there's no additional action required for the reader when a page with an interactive widget is opened.
Hey Tom, apologies for taking so long to reply. I think this can be achieved with some custom tags. I propose the following tags: disable-execution, auto-execute. These can be added to any cell, but let's say the header cell by convention.
