Dear list members,

I would like to add a tag to a block so I can easily select a few blocks and print them in another chapter.

In the below MWE I would like to print the normal (non-tagged) block in the first chapter. The second block with the tag [exam] should not be processed in the first chapter and only appear in the second chapter.

According to the wiki and reference manual it should be possible using either \useblocks or \selectblocks but I can't get it to work.
At this point you can hide tagged blocks.

This flushes all saved blocks and you can't exclude tagged blocks but it's possible to extend the mechanism an apply a default tag to each block which will allow selective output.

This was a bug (do you get a error message in your document?) and should be fixed in the next beta.
