I've never used AwesomeWM but from a brief reading, maybe it could do part of what you want: "maybe select a group of windows and make them my current view". From what I understand, windows don't belong to a workspace, but a workspace is a collection of windows having a certain tag. A given window may have multiple tags, so it can belong to multiple workspaces.
