Thank you for your kind word Alex
Being detailed focused as I am I think a little warning is in its place here. Remember automations run under the user credentials of the user who added the automation to the board.
So when user A added the automation and user B changed the status to trigger the board creation and chooses either “private” or “shareable” board type, the board will be created with user A being the owner of the boards and user B (who changed the status) wondering why she/he has no access to it.
The phenomena can be solved by either creating an App yourself or by using something like Integromat where you can get the userID of the user B (the one that triggers the board creation) and add that user to the list of board owners.
