As a Roblox developer, it is currently too hard to make good looking scrolling frame scrollbars without uploading a bunch of images.
You know how ImageLabels can do 9-Slicing, well why not add 3-Slicing for scrolling frames. This would make it so you only need to upload a single image for a scrollbar, and you’d be able to edit the color of it like you can with ImageLabels and pretty much every other UI element. It’d also remove the clutter from the properties panel.
There’d be a property called SliceCentre which would be the same as it is in an ImageLabel but it wouldn’t have the x coordinates. The first coordinate would be the bottom of the top of the scrollbar and the second coordinate would be the top of the bottom of the scrollbar. The top and bottom don’t get stretched but the middle does
Oh and for the people who are gonna say “no this cant be done loads of old games will break nooooo”, just hide and deprecate the old properties from the properties panel and only show the new one.
