+For early adopters, I'm trying to publish intermediate builds on a testing channel. Builds are fully tested, but I don't want to publish an official release on every commit :wink:. To proceed, go to <kbd>File</kbd>, <kbd>Settings</kbd>, <kbd>Plugins</kbd>, <kbd>Manage Plugin Repositories...</kbd> and add the `https://plugins.jetbrains.com/plugins/extra-icons-testing/list` repository. Expect 0 to 2 intermediate builds between two official releases, mainly to get bugfixes asap.
