         This is beta software, if not alpha. It kinda works, but there will be issues. Feel free to help out with a patch, or by filing bug reports.
         Known issues include:
 
-        * Editing long lines will blow up. Don't try to edit anything longer than the terminal is wide.
-        * There is no fullscreen editing, so verbatim blocks in twig will probably not work well either.
         * Comments are not preserved.
         * Files are overwritten without confirmation.
         * There is no command mode, no search.
         * Some things just don't work yet.
         * Unhandled keys will appear in the bottom left of the screen with a delay.
-        * Folding is not yet implemented.
         * There are crashes, and lock-ups. Data corruption is a possibility.
