I don’t support this, you can easily clone a frame and just use reclass by Elttob to change it into a different UI element:
Even if that’s too tedious why would Roblox want to implement this feature? It would only help in a small amount of cases.
Offset is probably even more useful than scale. Offset and AspectRatios are the 2 things you need to make a UI element to be consistent across all devices.
