Footnote legibility issues

[RubenVerborgh]

I'm currently reading @surilindur's https://github.com/surilindur/eswc-demo-paper/ and

is hard to read. Two issues:

• References to multiple footnotes need commas in between (cfr. references), but this requires syntactical support (e.g., [^fn1,^fn2] or [^fn1 ^fn2], whatever is consistent with multiple references)
• The underline breaks text flow; it is at hyphen height and looks like a hyphen.
  • Proposed resolution: only underline on hover (and add tiny left padding before to further improve legibility)

Also the actual footnotes are unnumbered in the HTML rendering:
