1. In the build.gradle.kts file, the intellij block can be simplified by using the intellij extension function provided by the IntelliJ Gradle Plugin. This function allows you to configure the IntelliJ plugin version, target IDE platform, and plugin dependencies in a more concise way. Here's an example of how the intellij block can be simplified:

intellij {
    version.set("2022.2.5")
    type.set("IC") // Target IDE Platform

    plugins {
        // Plugin Dependencies
    }
}

2. In the build.gradle.kts file, the signPlugin and publishPlugin tasks can be configured using the with function to avoid repeating the set method for each property. Here's an example of how the signPlugin and publishPlugin tasks can be configured:

tasks {
    patchPluginXml {
        sinceBuild.set("222")
        untilBuild.set("232.*")
    }

    with(signPlugin) {
        certificateChain.set(System.getenv("CERTIFICATE_CHAIN"))
        privateKey.set(System.getenv("PRIVATE_KEY"))
        password.set(System.getenv("PRIVATE_KEY_PASSWORD"))
    }

    with(publishPlugin) {
        token.set(System.getenv("PUBLISH_TOKEN"))
    }
}

3. In the gradle.properties file, the ARTIFACTORY_URL_SUFFIX property can be removed as it is not used in the code.

4. In the plugin.xml file, the extensions element can be removed as it is empty and not used in the code.

5. In the pluginIcon.svg file, the fill attribute of the <path> elements can be simplified by using a CSS class or inline styles. This can make the SVG code more readable and maintainable. Here's an example of how the fill attribute can be simplified:

<path class="fill-primary" d="..." />

or

<path style="fill: #F2C744;" d="..." />

By following these steps, the code can be simplified and made more concise.

We want to add this functionality to the skate plugin, not as a separate plugin :)
