First thank you for the kind words. Secondly I most definitely understand your dilema. I undestand what it takes to keep APIs clean and maintaintable and I can appreciate your desire to maintain Dolphin's in such manner. However, I can most definitely tell you that the solution you suggested is a complete non-starter for me. Though the solution might seem the cleanest way to handle this issue, duplicating the work the embedded part already performs penalizes those Konqueror users who have enabled the directory filter plugin (the default) unnecessarily. That would not only be true for local file systems, but also remote ones that support listing like FTP and SFTP. To me that is simply not acceptable. The reason I use a hack in the directory filter plugin to locate the KDirLister from the part was to avoid the very exact thing you suggested above. Anyhow, I have split out the notification related code into its own extension as you can see in REVIEW:106288. That way the filtering extension can stand on its own and if you guys still disagree with a new solution I came up with to solve this issue, then at least the filtering extension can be committed. I will post a new review for the implementation of the notification extension. - Dawit ----------------------------------------------------------- This is an automatically generated e-mail.
