As a Roblox developer, it is currently hard to find a good match of colors in the script editor, (personally) or to match them with other script editors, like Visual Studio Code. I’ve noticed that about 80% of the script editor is comprised of text and keyword colors. Now, naturally, I can expect there to be many keyword colors to be found in the script editor. Still, the text color takes up a lot of things that could be color-coded, such as variable names and parameters.
Maintaining a good appearance is very important to development, in my opinion, and it can be irritable to see too much of little colors. Furthermore, having separate colors should make it easier to identify different things (obviously), which is extremely important.
I think a good change would be to make it similar to the Eclipse IDE’s syntax highlighting options, which are very flexible. Having not poked around with the Visual Studio 2019’s color options, I can’t rate it. Here’s an example of a Monokai based theme in Visual Studio Code, which I think shows examples of what could be color-coded. Take note of the parameter colors, as the highlight of the image, in my opinion, is the function. The function name gets it’s own color, and the parameters within the declaration get their own color as well.
TL;DR: Giving separate things, such as variables their own colors in Studio would be a massive quality of life improvement, as it is not as customizable as it should be.
This seems like something that would fit into the “full script editor upgrade” found on the roadmap.
