New plugin: Overdue

Hi all,

I wanted to share a plugin I wrote called overdue which is available in the Community Plugins catalog.

I created this plugin to to aid my use of Obsidian as a task tracker. The plugin marks checkbox items as [[Overdue]] if you do not check them off by their due date.

For instance, say you have items like the following:

# In file 2020-01-01.md

- [x] Something I completed
- [ ] Something I didn't

# In another-file.md

- [x] Something else I completed [[2020-01-02]]
- [ ] Something else I forgot about [[2020-02-15]]

When the plugin runs any time after January 1st, 2020 local time, it will make the following changes:

# In file 2020-01-01.md

- [x] Something I completed
- [ ] Something I didn't [[Overdue]]

# In another-file.md

- [x] Something else I completed [[2020-01-02]]
- [ ] Something else I forgot about [[2020-02-15]] [[Overdue]]

The plugin runs automatically just after midnight to update your pages. You can also trigger the plugin using Overdue: Mark overdue items in the Obsidian command palette.

Opening a backlinks panel for the Overdue page shows all of your overdue items in one location.

The plugin only adds [[Overdue]] references, never removes them. When you complete an overdue item, check it off and delete the [[Overdue]] text to stop it from appearing in the overdue backlinks.
