The Unigui team has been studying a way to make its layout responsive for a long time (just look at the 2020 and 2021 roadmap).
Recently, TMS has added TTMSFNCResponsiveManager (available for VCL, FMX, Web) to its components.
Couldn't something similar be added to Unigui? It seems to me that migrating traditional Unigui apps to a responsive layout wouldn't be too much work as a similar solution.
