Ability to modify icons & color scheme?

[Cursdd]

Doesn't even have to be like a full blown thing like vs code. Something similar to making mc resource packs would honestly work perfectly imo. Something like you can change the png (like a resource pack) of an icon, and for color schemes you could have a file for the general types of keywords, like commands (e.g. execute would be blue), numbers / data types, and then the corresponding color. Also, if this does get added, the ability to modify the color of any keyword manually, or, like mentioned above, the type of keyword it is.
