In older versions of airdc and fuldc there was a nice feature to log only specific details from mainchat.
If you typed /lastlog in main a new tab would open, and the recorded lines were displayed.
In the settings you could easily add and edit words to trigger the lastlog-function, and you could also decide how these words would be highlighted in the mainchat and if a popup should be shown as notification.
This was a great feature, as you could add words that were of interest to you and in the morning you could just enter /lastlog to see the important stuff you missed while sleeping.
