In the API Docs I stumpled upon the possibility to set the viewtype to 1 | 2 | 4. Are those List, Broadsheet and Graph? If so, is there a possibility to open the filtered cards directly in Supernotes. That would be the perfect shortcut until the custom collections are coming …
You are indeed correct, the view types are the following:
ViewDisplayType: LIST = 1 BROADSHEET = 2 GRAPH = 4
However this is not the same as opening the app with a certain view type, this is only for backend use to remember what you preferred view type is for a certain view.
Thank you for the clarification. Then I will probably have to wait for the custom collections.
