calendar view usability: the link to the actual snapshot is too hard to find
Consider an origin list view with a single visit, e.g., https://archive.softwareheritage.org/browse/origin/git/url/https://github.com/nokia/mesos-kafka/ It is really hard for a newcomer to find where to click to get to the snapshot content, because:
- the timeline view occupies a huge part of the screen, and in there only the timestamp (which are quite tiny) will lead to the content
- in the calendar view only one day out of 12 months worth of calendar is clickable
- the list view is far down the bottom of the page
We need to make more intuitive where one has to click to get to the content
