Projects often have icons, and IDEs and other tools are capable of showing the icon side-by-side with the project name.

For instance, IntelliJ IDEA and JetBrains Toolbox recognize .idea/icon.png and .idea/icon_dark.png files to show the icon. That works, however, it is not very portable across IDEs.

I suggest that editorconfig should add an option to specify the project icon.

For instance:

project_icon=path/to/icon.svg
project_icon_dark=path/to/icon_dark.svg

Then the icons could be configured once for all the tools that support editconfig.
