I can’t find any match to PN when it comes to usability, and this was just the kind of feature that got me trying other editors…

Here’s what I’d change, in priority order:
1. Pop it up upon match (less typing)
2. Add function parameters
3. Nevermind 2 and 3-letter words (save CPU)
4. Auto-end tags and braces (as an option)

To me this feature sort of duplicates TextClips, I hope they can be combined in the future.

Thanks again for putting this great editor together!
