I think we are very overdue for an update to GUIs. There are many properties that would eliminate the need for uploading images and loading images into games.These changes could also make games look a lot more professional and polished. I have listed them below:
Border Radius - Allows curved corners. Also create sub-properties to modify individual borders segments such as TopLeft, TopRight, BottomLeft, and BottomRight.
Drop Shadow - Allows a shadow to appear under GUI elements. Should take the shape of the GUI like GUIs with border radiuses. Also include sub-properties such as distance, strength, and possibly even angle.
Font - Allow upload of custom fonts. This is a big one because the current fonts can look cheap a lot of the time.
More Sub-Properties for Text-Shadow - We cannot currently edit text shadow properties. Would really be nice to be able to edit shadow strength and size. (distance)
These features would really benefit me personally as a developer and many other developers who are willing to utilize these features. Currently, I find myself uploading a lot of images to work around the lack of GUI features and it just means that players have to load more images into the game. I really hope the team at Roblox will take these ideas into consideration. I do a lot of UI design, so these added properties would save me a lot of time on making my UI look great. The current state of GUI elements has a lot of limitations and it makes things difficult. Thanks to anyone who supports!
