Every customer so far has requested the ability to upload multiple files at the same time to attach to a case, and so every team has had to add that option within a process step. An improvement would be to enhance the existing OOTB case-wide attachments interface (using PegaSocial-Document) to support multi-upload (in a similar way that Data-WorkAttach-File did). This gadget is in the right-hand side Utilities panel of the Case UI in the Cosmos Portal, and has the header "Files & Documents".
In addition, it would be nice to be able to assign categories to PegaSocial-Documents in the same way that the old-style pxAttachContent control allowed you to assign categories to Data-WorkAttach-File.
