Software for browsing documents online, focused on readability.

Would support (a subset of) HTML, Gemini, Gopher, Markdown, PDF, Plaintext, and maybe others?

Inspirations, things to look at are:

• Firefox's reader view
  • IE what elements it is using and how it deals with problems
  • I don't necessarily want to put to much effort into supporting badly made websites though, tbh
• The Kristall 'small-Internet' browser MasterQ32/kristall
  • I like the layout with document outline on the left, document in the middle, and history and bookmarks on the right (see this image with a massive filename).
  • tbh it's almost perfect
• The Dat-based scientific papers reader sciencefair-land/sciencefair
  • The way it extracts and displays figures is interesting.

Support:

• h*
• ol, li, dl
• abbr
• main, section, article, aside, nav…
• audio and video
• base
• a and target
• q and blockquote
• pre and code
• table stuff
• dfn
• em, strong
• figure
• cite
• del / ins
• kbd
• mark
• meter (now there's a new one to me!)
• samp
• details / summary
• time

Ignore:

• css?
• stuff like divs and spans
• js, canvas
• form stuff?
• i, b (but maybe need to for olds sake?)
• iframe
• image maps
• slot

• Show document outline, built from heading hierarchy
• Show documents' metadata: author, title, keywords, description, last edit date
• Bookmarks, history
• View source, download
• …
