General information

• App version: 1.4.0 F-Droid
• System: Android 5.1.1, Samsung Galaxy J1 ace

Description

It would be nice to have a short-cut in the bottom toolbar to start creating a check-list (- [ ] ) just like the ones that are available for creating a ordered/unordered list in the bottom toolbar.

Also, it would be nice to have the prefix (- [ ] ) for the second item in the list automatically appended after I hit enter in the first item. Just like the ordered/unordered lists.
