UPDATE: This plugin will remain functional, but I will be focusing on obsidian-multi-properties instead, which serves very similar functionality. Multi Tag will be around for anyone who wants to use inline tags.

When installed, right-clicking on a folder will bring up an option to add a tag to all notes within a folder. Upon clicking this, a message will pop up asking you to add a tag. You may add your tag, and it will be appended to each note in the folder.

You can also select multiple notes with Shift+Mouse, and right-click the selection to get the same efect.

If you want your tags to be appended to the frontmatter via YAML/Properties, there is a toggle for this in the plugin's Settings menu. "YAML" will add the tags as a property, and "Inline" will append each tag to the bottom of the note. Note that "YAML" checks for duplicate tags, but "Inline" does not.

Installation:

This project is available as a community plugin in Obsidian that can be installed directly in the app, under the name Multi Tag.

If you wish to install it manually,

1. Download the latest release.
2. Extract the folder within the release and add it to [yourVault]/.obsidian/plugins/.

Ideas for Features:

• Settings option for whether tag appears in YAML or bottom of file.

Next Steps:

• Update obsidian typing so "files-menu" is properly implemented.
• Allow user to change between YAML/Inline directly from the form instead of needing to go into Settings.
• Clean up code. It's kind of messy right now.
• Try converting to front-end framework to make forms easier to manage. Will try Svelte.
• Add tests.
