Seconding on this, as already mentioned above my suggestion is to implement a title YAML tag to use in visualization-related scenarios instead of plain filenames. This solution is also compliant to ones adopted by other tools like pandoc and Zettlr, so it’s a step forward compatibility-wise too.
Plus, which YAML tags are supported should be documented in a dedicated page, maybe into an in-depth introduction about how front-matters work?
Thank you for your job!
