Use case or problem

I was trying to look for which line(s) have a tag for the currently open file.

Proposed solution

A new filter that shows “tags on this page”.

This filter would be is hierarchical, and able to fold, just like current Tag View panel. It would show the line number and line contents which contains the tag. Clicking on a line number scrolls to that line in view.

Example:

  • parent tag
    • nested tag
      • 12: line contents
      • 23: line contents

Options for the this filter:

  • same as the current plugin’s panel
  • show line number

Current workaround (optional)

Create a inline search query to find the tags in this file:

```query
path: "path/to/file" /#\w+/
```
