-   This is my attempt to make 4coder work close enough to Emacs
-   for me to switch!
+   - Display:
+     - Jumping to subsequent errors in a file seems to jump to an unrelated position
+       then scroll back to the actual position, which results in lots of extra scrolling
+     - Need a way of highlighting the current line like Emacs does for the benefit
+       of people on The Stream(TM)
+     - Need a way of changing some things visually so we can indicate the modal state (this has
+       to be something very obvious - ideally something like
+       1) Change the line highlight color
+       2) In modal mode, highlight the whole selected region (mark to cursor) potentially?
+     - Some way to recenter the view so that the line containing the cursor becomes the
+       center line vertically.
+     - NOTE / IMPORTANT / TODO highlighting?  Ability to customize?  Whatever.
 
-   NOTE(casey): Microsoft/Windows is poopsauce.
+   - Indentation:
+     - Multiple // lines don't seem to indent properly.  The first one will go to the correct place, but the subsequent ones will go to the first column regardless?
+     - Would like the option to indent to hanging parentheses, equals signs, etc. instead of
+       always just "one tab in from the previous line".
+     - Need to have better indentation / wrapping control for typing in comments. 
+       Right now it's a bit worse than Emacs, which does automatically put you at
+       the same margin as the prev. line (4coder just goes back to column 1).  It'd
+       be nice if it got _better_ than Emacs, with no need to manually flow comments,
+       etc.

+     - Have buffers normalize slashes to always be forward-slash - right now I'm doing this manually
 
-   - Have buffers normalize slashes to always be forward-slash
-     - Cursor setting seems to do no movement first time, and then weird scrolling behavior on

-     used buffer that is not currently displayed in a view.
