As a Roblox developer, it is impossible (afaik) to make the Text property of a GUI element be a gradient using RichText. Adding this feature will make it much easier to add a gradient to text for those of us who prefer to use RichText.
If this issue is addressed, it would improve my development experience because gradients would be a lot easier to create.
Example Usage
(Kinda like CSS!)
<font color="linear-gradient(90deg, rgba(255,158,0,1) 0%, rgba(168,255,0,1) 100%)">Play!</font>
