The topic customization doesn't appear to allow for subfoldering and the topic itself requires a website address so it is not technically a folder either. How to add our current bookmarks with many subfolders to the sam bar ?This review is for a previous version of the add-on (2.2.1). This user has other reviews of this add-on.
1) Real sorry, but currently samfind doesn't support subfolders, it allows only for top-level folders. This is a (huge) limitation we are aware of, and we are working hard to resolve it for the next major version, hopefully out before summer.
2) Just to clarify, a topic in samfind requires at least one website, hence the "website address" you mention is not for the folder itself, but for the initial website required at folder creation. Again, we are investigating how to remove this constraint.
