Hi, I uploaded a new lmtx. Apart from a experimental intersection feature in the mp library (and metafun, more will be revealed when MS an I are okay with it) there is not that much news. I decided to turn some test code into a mechanism which is illustrated below. Adaptive boxes are hboxes that act a bit like glue which means that when we hook in e.g. a graphic it can be made to adapt. We can add some more methods if needed so maybe you see other usage. The interface is rather lightweight and the overhead is quite resonable.
