Fixed: Indentation issue with checklist items in previous versions. 0.0.1

Description: Resolved a bug where checking off a list item would not preserve the original indentation. Now, when an item is checked, the list will maintain its intended format.

Before Fix:

- list title
  - [ ] my item 1
- [X] ~~my item 2~~
  - [ ] my item 3
  - [X] ~~  my item 4~~

After Fix:
```

• list title
  • my item 1
  • my item 2
  • my item 3
