The app has two panes :
Compose (Left Pane): This is your "What You See Is What You Get" (WYSIWYG) editor. Here, you can apply formatting using toolbar buttons and menu options, and your text will instantly reflect those changes visually. This panel is ideal for users who prefer a more traditional word-processor experience.
Markdown (Right Pane): This panel displays the raw Markdown code that is generated as you work in the Compose pane. You can also directly type or paste Markdown into this panel, and the Compose pane will update to show you a preview of how it will look when rendered.
The two panes are synchronized, allowing for a seamless transition between visual editing and raw Markdown syntax.
Files can be saved in Markdown format. There is also a Recently Opened menu to make it easier to see recent work.
And there is a wide range of Markdown syntax supported :
Headings from level 1 to 6 are supported using the hash (#) symbol.
# Heading 1
## Heading 2
### Heading 3
#### Heading 4
##### Heading 5
###### Heading 6
