Welcome to the community! Before you start implementing a feature, take a look at https://dynalist.io/d/zUP-nIWu2FFoXH-oM7L7d9DM, as there may be a ready solution.
What you want to achieve is in the Locator plugin (https://bimlas.gitlab.io/tw5-locator/): you can filter the list by tags associated with the text you type in the search box, you can select multiple tags at once, and even in the Table of Contents it shows the tags of the currently listed tiddlers. Give it a try and if you have any comments, questions or ideas, feel free to let me know. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
