 ## STAGING
 
-* centering logic in view.c seems broken
+* implement mouse warping on search, jump to line, and focus change
 * implement new version of tfetch (plumb)
 * implement tide registrar
 * implement tctl command
-* implement mouse warping on search, jump to line, and focus change
 * gap buffer does not handle UTF-8 currently
 * Line - Get the current line number(s) containing the selection
 * refactor selection handling to avoid swapping manually (use buf_selbeg and buf_selend)
 * encode EOL setting in log entries?
+* centering logic in view.c seems slightly broken
