Apparently the codeblock macro has been replaced by code snippets.
Here's my question: you could configure codeblocks to be collapsable. Thus it was possible to hide a good chunk of code when the page opens and the user was able to expand the code that she was actually interested in.
For code snippets I cannot find an equivalent. Has this feature been removed?
If so, it must be put back, lest I will not be able to convert any of my pages to make use of the new editor.
