I know this isn’t really offering what you asked, but Rich Text does improve many of the failures of basic Text Gui instances. You can find it here: RichText [TextScaled Support Added]
Also, at RDC they announced some new fonts which offer a wider variety of UI design styles. I do think they should add properties for text shadows and maybe a constraint like UIBlur which blurs an ImageLabel, ImageButton, TextLabel, or TextButton.
I also think Roblox should invest in creating a flat icon catalog or something where UI developers can sell Roblox icons or use free ones made by Roblox.
