Explain the problem as you see it
In general, having the ability to connect an collect data nodes from anywhere in the workspace is the basis idea of Tana. In some cases there's a risk to loose tagged data you actually would like to collect and keep very easily by deleting nodes or their parent nodes.
Why is this a problem for you?
It's especially a problem if you are working in a team.
Let's give an example:
I'd have a supertag '#person' and everybody in the team would create #person nodes (e.g. in their #day node) while communicating with customers. As a company I would like to collect all contacts employees are having.
To collect all contacts I would obviously create a #person search node.
Problem, if someone would delete his node containing a #person node the contact information would be gone everywhere. In a team this happens a lot!
As a workaround I would need to open the #person search node, display the owners, and then move the nodes manually to a "save place" (e.g. Library/Contacts) manually.
Suggest a solution
As a user I would like to have the ability to configure the owner of a tag (e.g. Library/Contacts). By doing this every #person someone creates should be automatically moved to or directly created in his owner node.
