Looking for ideas for a browser extension icon. Problem is the very small size: should be understandable at around 48x48 pixels. Restrictions that I need to work with:

• I will draw it, so can’t be too complicated 🙂
• It is about markdown links so, something around the forms of brackets perhaps?
• Relatively simple shapes (for size and bcs my drawing skills)
• Not too many colours… But perhaps bright ones(?)
