Categories and Versions
[TODO: snapshot of nodebrowser showing the IO category]
[TODO: tooltip snap]
Also types are categorized. Sometimes you need to specify a type for a data hub. In rare cases you may need to also specify the category if several data types of the same name exist in different categories.
[TODO: type annotation snap]
A version is always shown in round brackets. The main reason for versions is that the author of a node wanted to keep the name as short as possible. Versions help separating the main idea of a node from the details how to use it. There may be several nodes that basically do the same thing but differ in how they do it.
