What is new in Copperlight 0.16

## New

- **Keys in notes:** ⌘B bold, ⌘I italic, ⌘E code, ⌘K link, ⌘1 to ⌘3 headings, ⌘⇧7 bullets, ⌘⇧9 numbers, ⌘⇧L checkboxes, ⌘' quotes. Each writes the Markdown for you, and pressed again takes it off. The file stays plain text, and ⌘Z undoes it.
- **Enter goes on with a list:** the next bullet, number or checkbox. Enter on an empty one ends the list, and ⌥Enter starts a plain line.
- **Text size in notes:** ⌘+ and ⌘- for bigger and smaller text, ⌘0 for the normal size. It's one size for every note, and it stays until you change it.

## Changed

- A note's title reads without its Markdown: `# **Groceries**` shows as Groceries.

## Fixed

- ⌘Z in a note: what you undid wasn't always saved, and could come back when the note reopened.
- `***bold italic***` draws as both, and bold and italic draw inside headings.
- If the clipboard history can't be read, it says so instead of showing an empty list.
