Thanks for the patch! Could you update the PR title to use MINOR: as the prefix?

@Pankraz76 thanks for your contribution. I don't quite understand the purpose of having the icon in Intellij. Could you share your thoughts with me?

Thanks for the response. It’s just a nice little gimmick to improve the look and feel. It helps (me) quickly recognize projects when switching between them.

I can’t say for sure if it’s good for this project. The only feedback I’ve received so far has been positive, and these changes have always been accepted. The only downside is having IDE-specific configs in the repo, which is generally avoided. In this case, all the projects make an exception to support this.

I just noticed this by accident as well so I like to spread the learning:

Very cool! I didn't know this was possible
