There's nothing about symbolic links that means they should inherently be made relative instead of absolute, and both types of symlink can be useful, so it's a feature request not a bug report.
(e.g. What if you want a symlink that always points to the same place even if you move it around?)
[quote]Again, you seem to have overlooked the other problem I mentioned:
In FlatView Mode (folders and files alltogather, Mixed or Grouped) Filter does not filter out Folders, only Files. Is this a bug or not. Should I fill a bug report for this or I am getting this wrong?[/quote]
Turn on Preferences / Miscellaneous / Advanced: flatview_folder_filters. (Also note that if a folder is filtered out, all files and folders below it will be filtered out as well. That confused so many people in the past that flat-view was made to only filter files by default, unless that setting was changed.)
BTW, this is part of the reason we ask that people post one question per thread (in general; of course, it the questions are closely related then it makes sense to ask them both in the same thread).
