This is a small plugin for Obsidian that displays the set of dangling links in your current vault in a side-panel -- links you've put in a note somewhere that don't currently point to anything in the vault.
Dangling links may be typos or they may be links you intended to make a note for but forgot to get to. Either way, it can be nice to have a list of them to work with.
The panel is accessed with the "Dangling links: Open view" command, or by clicking the broken-link ribbon icon. Dangling links can be grouped by the file or folder they occur in, or can be shown as a list of dangling links and their reference and you can click each occurrence to navigate to it.
You are also able to collapse each item or ignore complete folders from the settings page.
I've marked this as requiring obsidian v0.9.15 because that's what I have. If you get it working on an earlier one, I'm happy to reduce that number. I don't have a lot of time to spend testing versions though and I don't see a big reason to stick with old versions.
