Missing/Incomplete API Integrations

Hi,

Maybe I have just missed something, but as far as I can tell the following is missing from the Scale Cloud API which is making it's usage a bit... challenging. 

1. You can only fetch test case versions, cannot create new ones
2. Cannot create Parameters for Test Scripts 
3. Cannot fetch Custom Field definitions
4. Paginated requests don't support basic searching (Bit pointless without it...)
5. Can't search for test cases which have no parent folder
6. Can't update Owner/Priority after creation (Could just be my integration being incorrect)

There could be more, but could anyone tell me if I am losing my mind, or maybe just looking at old documentation? https://support.smartbear.com/zephyr-scale-cloud/api-docs/#section/Introduction

Maybe if there is more missing you'd want to add it to this thread and I'll do a big support ticket.

Thanks
