Wanted to give a slight update on things regarding the site linked in the op site, under the title "Grammar Reference".
Concept image note conversion status:
Basic volume: 60/203 concepts converted.
Only the first 20 concepts reflect this on the site, I'll update the other 40 tomorrow. Otherwise, progress seems to be going okay and the tables and conjugation charts convert pretty well to text.
Also, I've changed the volume pages slightly, tweaking the colouration to make it a little easier on the eyes, confined the content into tighter margins and added a "night mode" version of each page. You can switch back and forth between the day and night versions with a link above the table of contents. Figured that for those reading at night, etc. might want something a little easier on the eyes. Feel free to make any related suggestions.
Pic related is a screenshot of the same section of the Basic volume page, side by side so you can see the difference between the night and day versions.
