 - ask user if he really wants to quit even though he has an unsaved buffer - popup window
 - add plumb rules for some web stuff
 - test the code editor: try writing in it, try browsing in it, create test tooling
-- event serialization to lua object format
 - Execute enclosure which is going to execute on every keypress, modification
-- Store editor metadata in user accessible buffers? (read only)
 - Find matches using grep, change things in that buffer then apply those changes to all items
 - group history entries so the you can rollback through multiple ones at once and not waste time on skipping whitespace trimming or deleting every character
 
+- Fuzzy search buffer which uses titlebar as query!
 - Check if file exists in ApplyRules otherwise return null
+- Store editor metadata in user accessible buffers? (read only)
 - Add the event buffer with serialized events
+- event serialization to lua object format
 - Gotos, jumping between views should preserve cursors
 
 - OnWindowCommand allow config user to overwrite the WindowCommand keybinding, introduce his own
