First the suggestion: I just opened the log viewer and noticed that I now have logs from 2006 to 2008 saved in there, one folder per month.
Why aren't those log folders sorted chronologically ? In my opinion that would be the better (in terms of user friendliness) choice than sorting them alphabetically in the tree view.
To visualize:
Current (Alphabetical order) Better (Chronological order)
And now the other thing I noticed was that on a PC running a 'german' Windows XP with the English version of WLM installed and the Interface Language set to English in the Messenger Plus! Preferences, the chat logs are still saved in folders named after the german months ('Januar', 'Februar', 'März',... instead of 'January', 'February', 'March'...). Not sure if this can be classified as bug, I consider it a minor inconsistency, just something I noticed.
