+
+## Features
+
+1. Add support for saving filse - Kind of important that
+2. Show whether a file has been saved or not
+    I think an interesting way to do this is to take a hash of all the text in the current buffer
+    and then do the same for the text when the file was last saved/opened and compare them, if they are
+    different we know that the file has been changed in the buffer
+3. Add shortcuts
+4. Add config file - Font and themes
+5. Add menu bar
+6. Add support for opening files from the editor - drag and drop support?
+8. Syntax highlighting would be neat?
+
+## Bugs
+
+1. There is a bug when wrapping text, we don't add new lines so the text get garbled.  It's fine when there is space between lines that are being wrapped but when there are multiple lines next to each other that need to be wrapped the text gets messed up
