Version: (using KDE KDE 3.5.0) Installed from: Ubuntu Packages The number of Filter Criteria that can be used in KMail's Filters is limited to 8 (the "More" button becomes disabled when the number of criteria is at 8). The only possible reason I can see for this restriction is consideration of users with low screen resolutions, and this can be solved by placing the filter criteria in a QScrollView.
