Hi,
I wanted to have an overview of my current projects and their progress.
So I have notes representing projects which I tag with #current_project in the front matter:
---
tags: #current_project
---
Then I list them with Dataview, printing a filled circle for each completed task and a hollow circle for each incomplete task:
dataview
LIST replace(replace(replace(string(map(file.tasks.completed, (t) => t = true)), "true", "●"), "false", "○"), ", ", "") FROM #current_project
Here is an example:

Simple and useful, I think
.
(Can undoubtedly be implemented more simply with JS, but I’m not there yet.)
