[REQUEST] Nested task lists

[foobargeez]

Is your feature request related to a problem? Please describe.
Do you have nested task list on roadmap? I use this quite a bit in markdown editors and was wondering if it can be brought to Yana as well ..

Describe the solution you'd like
Move task to right/left via keyboard shortcuts or by clicking on a button

Additional context
Looking for something like this ..

Because Yana uses atlaskit as editor frontend, and atlaskit does not support this feature, there currently is no way of bringing this to Yana.

However, I'm planning to bring an additional pure Markdown editor to Yana that uses bangle.dev as editor frontend, which would support those nested task lists. This is tracked by #25.
