Re: [RFC] [MdePkg] UefiLib: CreatePopUp

["Dong, Eric" <eric.dong@intel.com>]

Hi Felix,

Do you want to provide a new solution for CreatePopup or just want to split CreatePopup from UefiLib?  We already has a proposal to provide new API to replace CreatePopup. This new API will use modal form to paint the UI. Detail you can see the proposal in below link:
https://github.com/ydong10/doc/blob/master/Use%20Modal%20form%20for%20CreatePopup%20API.pptx

Thanks,
Eric
