 /* To do
- * - Add support for Index-Search
+ * - Config file
+ * - User and system-wide bookmarks
+ * - Include history, user bookmarks, system-wide bookmarks in typeahead suggestions
  * - Add sysop configurable host whitelist for telnet selectors (not the telnet addresses, but the gopher server's hostname)
  * - Improve address input (brighter, autodelete) (typeahead.js)
- * - Include history / bookmarks / sysop mandated entries in typeahead address suggestions
  * - Improve highlight visibility
  * - Shift-Tab?  Would have to store escaped state in input loop (I think)
- * - Push/pop bbs.system_status; set SS_MOFF for duration of session
- *   - Maybe have a pending notifications thingy
