# 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.
