Workspace studio allows sharing credentials via credentials manager between tools launched from this app. Also, all tools launched from WSS should support AES256. Are you please looking for credentials sharing also between the old tools or is there some insufficiency?
My apologies, I have been using the Toolset Launch Pad and not the Workspace Studio! This is so much better! There is support for 256 AES and the credentials are shared. Thank you for pointing this out.
