I'm not sure if either of the things you linked would solve this specific problem but I also only skimmed the pages you linked. For example the Jekyll plugin for the timestamps: 1. Looks for a specific type of post and then it scans the body of the post 2. Looks for a specific header on the page and then grabs the list right after that header using an xpath selector (no special classes needed) 3. Goes through all of the elements in the list 4. Parses out the timestamp from the line and changes the timestamp into a link with a data attribute containing a specific timestamp format The code for this is here: https://github.com/nickjj/runninginproduction.com/blob/master/_plugins/jekyll-audioseek.rb#L21-L37 https://github.com/nickjj/runninginproduction.com/blob/maste... There's no custom Markdown or even classes added to the list or post because it lets you naturally write your Markdown list how you would if the feature didn't exist, and the plugin's goal is to add in that new behavior behind the scenes. This lets me keep all of my posts really clean[0]. It would be super interesting to see a Hugo equivalent for the audio_seek custom filter. I don't expect you to spend your Sunday afternoon writing such a thing but it would be cool to see a direct comparison of how you would implement it with Hugo. It might get more folks to move to Hugo too, because the main thing that keeps me using Jekyll is the ability to create adhoc customizations without needing to fork Jekyll.
