Two Features I Wish Nano Had

### Feature 1: **Code Folding**
Introduce a **code folding** feature to allow collapsing and expanding
sections of code or text based on indentation. This would be similar to how
many modern IDEs manage functions, loops, or paragraphs. Users could
collapse adjacent lines with the same indentation level, making it easier
to navigate and focus on specific parts of large files.

### Feature 2: **Multiple Cursors Editing**
Implement **multiple cursors editing**, as seen in editors like Sublime
Text and Kakoune. This feature would allow users to place multiple cursors
on different lines or positions simultaneously, enabling the execution of
identical commands or text manipulations across those locations. This could
greatly enhance productivity for simple tasks.
