Hi @den, after more testing the plugin in my own vault, I’ve just released version 0.2.1. You can download the three files (main.js, manifest.json, versions.json) from https://github.com/visini/obsidian-icons-plugin/releases/latest and place them in your vault’s plugin folder: YourVault/.obsidian/plugins/obsidian-icons-plugin/ (create the folder obsidian-icons-plugin if it does not yet exist). Then, reload obsidian and activate it via Third-Party Plugins settings.
Let me know how it goes! I’d be glad to assist you in getting this working so you can provide some feedback.
