This will open a @window listing all your .log files in a side list box. By double clicking the one you will then see what is in it in the main part of the @window. Also by chosing "Stats" in the @window menu it will tell you how many .log files you have. The title of the @window changes to let you know which one you are viewing and for which network.

Original idea and basis from http://www.hawkee.com/snippet/8441/ I edited it a bit and made some modifications and felt I would share it.

Update: Added search feature for Display area and List area. Added a reset feature for Display area and List area.

Update 23May2011: Added ability to delete log files ( send to Recycle Bin ) , fixed a bug and cleaned a bit of the code.

Update 14Jul11: Fixed issue if a person PMing you has a nick of 1 letter/number/symbol.

Update 13Feb12: Fixed issue if channel has "." in the title.

Update 9Sep14: Added ability to sort side list by default , channels only, Query/PM only or @Windows only. The reset feature allows you to reset to any of the mention options.
