As a Roblox developer, it is currently too hard to create a user interface that uses a scrolling frame, because anything that gets resized via scale will get stretched with the canvas when you increase the canvas size. This makes it incredibly frustrating to work with, as I have to keep mobile/high res screen compatibility in mind, while also making sure to use things like uiaspectratioconstraint.
My solution? IgnoreCanvasYScale. IgnoreCanvasYScale would be a boolvalue in scrollingframes, that would allow all of the ui inside of it to scale as if the CanvasSize.Y was always set to {1,0}.
If Roblox is able to address this issue, it would improve my development experience because I could create the ui in the scrolling frame just like anything else. It would cause much less frustration, and would significantly improve the speed of scrolling frame ui creation.
A particular use case is when converting a grid that did not previously need to scroll, that now does.
If the grid’s ui was all sized using scale, then chances are doing a proper 1:1 conversion into an endless scrollingframe would be a massive headache.
