New feature:

- `Sync on Editor save` has been implemented
- Now we can use the `Hidden file sync` and the `Customization sync` cooperatively.
- We can ignore specific plugins in Customization sync.
- Now the message of leftover conflicted files accepts our click.

Refactored:
- Parallelism functions made more explicit.
- Type errors have been reduced.

Fixed:
- Now documents would not be overwritten if they are conflicted.
- Some error messages have been fixed.
- Missing dialogue titles have been shown now.
