 ## Tell me of the future
 
 All the above works. Here's what's coming next:
 
-- [ ] Note edit command
-- [ ] Combining find and grep, to match either one
-- [ ] Pipe filenames (from `notes find` or `notes grep` or anything else) to `notes open` to open all matching notes 
+- [ ] Combining find and grep, to match anything one
+- [ ] More interesting and nicer looking file/grep search result formatting (...only when not piping?)
+- [ ] Make the file extension optional
 - [ ] Bash/zsh command autocompletion
 - [ ] Bash/zsh note name autocompletion
-- [ ] Shorthand aliases `notes o`, `notes g`, `notes n` 
-- [ ] Interactive mode: `notes` should open a scrollable list of notes, open your editor when you pick one, and reappear after you close it.
