The upload option in SOLIDWORKS PDM Professional 2016 Beta1 has an option called "Add Files" which allows a user to add additional files to the current list of files which will be uploaded and checked in via the Web2 interface. This makes sense when you are about to upload a document.

However, after uploading and checking in the files from the dialog, the Add Files button remains active, allowing the user to choose more files to upload. I was initially confused by the terminology "Add Files" since I also see a "Status" Indicating "Adding". So I was confused about what Add Files meant and if it was in reference to the Status. I think the Add Files button should either change to "Add more files" after completing the upload, or rather, should probably state "Select files" or "Browse for Files" or "Add Files to list". I would prefer "Select Files to Upload".
