Some users have asked me what modifiers are. They don't seem to know this concept in a renaming tool and are a little bit confused by it.
I will try to explain what the modifiers do and why I implemented the renaming tool in such a way.
Update: Error Handling Wrongly placed modifiers are highlighted now, so you can easily see if you made a mistake. A modifier is invalid when it is not added directly behind an option or an option-modifier pair.
This is a companion discussion topic for the original entry at https://www.digikam.org/news/2009-11-28_notes_about_modifiers_in_the_digikam_rename_tool/
