- # Q: How can I get a very smooth and clean upgrade?
- #
- # A: /set -clear upgrade_separator
- # /set upgrade_suppress_join ON (default)
- # /set channel_sync OFF
-
- # Q: Can I use color in the upgrade_separator?
- # Q: Is it possible to save my command history?
- # Q: Can I prevent the screen from blinking?
- # Q: Can you make it faster?
- #
- # A: Probably not, but if you can do it, tell me how.
