I got a suggestion : When you want to copy or drag&drop existing documents to a new deal, this process is relatively complicated. Pleas implement a function that automatically creates this folder.
Alternatively, maybe a good compromise. In Deal/Document there is a " + Button" where you can select Add Link or Add File
There should be a third selection named Create Folder
Currently copying existing files e.g. from an existing deal to a new deal within windows explorer is complicated.
First you have to Add an existing file (I always use a 1 kB File that I delete later on) to trigger OCM to create that directory. Then windows explorer is able to access this new folder and then it is easy to do the required file copies.
