When using the UIGridLayout, the padding is also applied to the first frame on each row. This becomes a problem when you use a UIGridLayout with HorizontalAlignment being Left in a ScrollingFrame as the first frame on each row isn’t truly starting on the Left as you can see in the image below.
This is a problem as it makes the ScrollingFrame look somewhat unnatural derailing the aesthetic of the UI.
My suggestion is an IgnorePaddingOnFirstFramePerRow propety for the UIGridLayout which when true will not apply padding to the first frame on each row.
