</div>

In an inject node (and any other node with typed input) I am able to select "number" as type and leave the field blank. I would expect that this is not valid but instead the node is saved. Why (saved, no error)? Wouldn…

Currently if I need several properties from the context store, each has to be read using a separate global.get('foo') call. It would clean up buch of my function nodes if it was possible to read all properties at once. T…

One major limitation of the join node is the lack of a timeout. For example, two paths should be received within 10 seconds. I feel this is important enough that it should be a core feature. It has enormous potential, es…

If the oneditprepare changes the number of ports on a node it is not persisted across refresh of diagrams. This should be persisted (maybe oneditprepare called on diagram load) or new onLoad function is added.
