I try to add notes to a Vuo composition to help me remember what each part does. From now on, I’m using comments by right-clicking on the composition and Insert Comment It works fine, but the node lines go over it, and it’s hard to read the content:
File > Open Example > Tschuri shows one example of organizing/labeling different parts of a composition with comments.
There are various ways you could reduce the amount of cables crossing over your comments. View > Hide Published Ports will hide the published port sidebars and their connected cables. You can also right-click on a cable and select Hide. Another option is to organize your composition into subcompositions.
