# Heading Level Adjust for Obsidian

A powerful and safe plugin to adjust Markdown heading levels and clean up your notes in Obsidian.

## Features

### 1. Heading Level Adjustment
Easily promote or demote headings within your selection or the current line.
- **Increase Heading Level**: Converts `#` to `##`, `##` to `###`, etc. (+1).
- **Decrease Heading Level**: Converts `##` to `#`, `###` to `##`, etc. (-1).
- **Custom Heading Level Adjust**: Opens a prompt to enter a custom delta (e.g., `-2` to demote two levels at once).
- **Composite Commands**: Combine heading adjustment and Markdown cleaning in one step.
    - **Increase heading level and clean**: Promotes headings (+1) and then cleans the selection.
    - **Decrease heading level and clean**: Demotes headings (-1) and then cleans the selection.
- **Safety First**: 
    - Prevents demoting below level 1 (`#`).
    - Prevents promoting beyond level 6 (`######`).
    - Operations are automatically cancelled if any line in the selection would violate these Markdown standards.

### 2. Markdown Cleaning
Clean up your notes with a single command.
- **Remove Dividers**: Automatically strips out horizontal rules (e.g., `---`, `***`, `___`).
- **Compress Empty Lines**: Collapses multiple consecutive empty lines into a single one.
- **Flexible Scope**: Works on the current selection or the entire document if nothing is selected.
