Users create folders there where it is not necessary. And not to follow everything.
Something can be configured in PDM so to regulate this question.
Of course there are templates, but it is a little not that.
For example, whether it is possible by means of Dispatch or other to cancel (or to hide) a command for creation of the folder under some conditions (for example in the root of vault or in the specified folder)?
Perhaps I am mistaken, but it seems to me that I met something like that (perhaps API or other). And now I cannot find.
