The following steps seem to produce unexpected behavior.
- In Markups module “Node” table, right click and choose either “Create new subject” or “Create new folder”.
- In Data module, locate newly created subject/folder and modify visibility or color.
- Return to Markups module and observe that the newly created subject/folder is no longer available.
Is it actually expected? Are markup folders not supposed to be modified via the Data module?
Edit: if a markup is subsequently made a child of the subject/folder via the Data module, then the folder/subject appears as expected in the Markups module.
