A Markdown app for "ToDo．md" - connected with Google Calendar and GitHub issues

Hello, I'm developing a Markdown note-taking and task management app, "Tasquet".

It is an online Markdown editor, but also has features like followings):

• When you paste a GitHub issue URL in a list item with a checkbox, the checkbox begins to be synced with the issue state (open/closed).
• When you create a list item including a time range, a corresponding Google Calendar event is automatically created and its title and time are synced bidirectionally.
• You can click the checkboxes, and drag and drop the items like task management tools or outliners.

Let's see an example below. Don't you usually write such todo.md files for your daily task management?

# My tasks
## 2020
### 03/20
- [x] Implement login form.
- [ ] Discussion with John from 12:00 to 13:00

And don't you think it is great if the listed items and tasks are synchronized with GitHub issue and Google Calendar automatically?

To organize tasks, I have tried tools like Asana, Jira, Quire, etc and admit their benefits, however, I finally ended up with Markdown - that is simple and lightweight.
So, I decided to develop Tasquet - a Markdown editor with features like Asana.

How do you think about this idea/app and do you want to use it?
