I'm no longer adding features to Life . There were too many feature requests for something that I want to be simple. I'm still updating my own Life events  tho'
1. You sort of use a striped-down Markdown(?) format, any reason for that? I use Markdown because it's also can be human-readable in some way, even though I don't really use a legit Markdown parser :P
2. Your date range format seems slightly different than mine. Maybe you need to document that somewhere :)
Some feature requests:
- Be able to resize the "code" pane and the preview
- Faster update of the timeline on change
- Use a standardized date format, like ISO 8601
I agree. If you're still processing a previous change you can defer subsequent updates (to what I assume is your polling mechanism), but when the event loop is idle the first one should be near-instantaneous.
The only reason it isn't instantaneous is because I'm regenerating everything in the iframe each time, as my initial goal was to just take the resultant HTML and paste it as a page on my personal site.
If it was part of the same document (not in a frame) it would be a vue component and update automatically/instantly.
I think a major issue is that pinching is very necessary to change the time scale if the horizontal axis is long enough (and it will be for browsing history), but pinch support outside the MacOS/iOS is sketchy at best. I haven't yet discovered the useful UX here. This was inspired by https://refresh.study (see: Browsing History section) which has a good mock of what it can look like.
If anyone has any other examples, I'd love to see it.
- ISO 8601 dates please, not everyone is in the US
- Color coding and/or topic headers so I can break it up into different sections for different types of events
- Support for emoji would be awesome, currently they break the site.
I saw other comments talking about ISO 8601, color coded events and one asking for other examples of timelines and it reminded me of the custom timeline I did for my previous personal website in 2017 if you're interested:
- Demo (gif): https://twitter.com/maxmre/status/919236332995702785 (it shows the "fisheye effect" that happens when hovering the timeline with the mouse)
- Code: https://github.com/blaze33/openblocv2/blob/master/src/compon..., I used React, D3.js and moment.js.
- Live version (surprisingly!) still hosted at https://www.openbloc.fr/home/about, click on the life timeline to expand it, might not totally work on mobile though as I recall, see above tweet in this case for the demo.
I'm thinking this would be a really simple way to display tasks and people involved in an incident or outage that itself involves many teams, but that would require that higher level of granularity.
Feature request #1 - color coding different types of events.
