ZFP - Request to be able to save layout of worklist (study/series) area

Customer can change the layout of study/series area of worklist manually, although it can not saved.So they requested to add the function to save per client system though it may be necessary to install NWI(Native Websocket Interface) etc on the client.
The requested site has multiple staff members using the same user for reference, then they think that it's better to do it per client system instead of per user.
Of course, I would be the best if you could provide both for per user and for per client.
