Important
This is the documentation for v3.5.0 and lower, for documentation for v4.0.0 and higher, see https://obsidian-html.github.io/
Fixed in v1.1.0
Issue
Using the feature Create Index from Directory Structure, you can navigate your notes by the folder structure on disk.
This works great, but if you have a non-md link, the javascript gets confused.
Fix
Starting with v1.1.0, non-md links are tagged as external, and thus avoid the tabulation javascript code that cannot deal with non-md files.
