  • (2020-03-11) Paul White: The idea is great, but unfortunately not working on new Gmail interface. I make extensive use of labels to track 100s of mails from system health checks. Hopefully someone finds a work around. Paul
  • (2018-01-18) David Brodbeck: Really basic, but also really handy. I'm a system administrator and get a lot of reports with formatted ASCII tables, etc. in my email. This lets me make them properly readable again.
  • (2016-08-08) Jim Kuzeja: Pretty good if you use filters to autolabel your messages. I have it set up to show various automated reports in monospaced fonts so the columns line up nicely again.

  • (2018-05-24, v:0.7) Cengiz Can: New GMail
    Please update the extension to support new GMail UI design. (As I see, `font` attribute is not getting overridden because it moved to a higher HTML node)
  • (2018-05-19, v:0.7) Christopher Johnson: update for new Gmail?
    Extension does not appear to work with the new Gmail interface. Any chance for an update?
  • (2016-08-08, v:0.7) Jim Kuzeja: Match everything but default to !Styled
    The addition of the "Styled" button that can be toggled on and off is useful by itself. If it were on *every* message but initialized to !Styled, then it could be a de facto "Show this message in monospace (or larger, or...)" button.
  • (2016-08-08, v:0.7) Jim Kuzeja: Match on other fields than Label
    Matching on fields other than the label would be useful. For instance, if Joe always sends me tabular data, then "From: Joe" would be very handy.
  • (2016-08-08, v:0.7) Jim Kuzeja: glob or regex in label match
    Some rudimentary pattern matching for labels could be very handy for those of us who subcategorize within labels (e.g., Notifications/machine1, Notifications/machine2, ... would become Notifications/* [or ".*"])
