For example, I am going to this webpage:

https://data.guix.gnu.org/repository/1/branch/master/package/docker

And from that page, I have to click to say (More information) below
this 2020-04-20 20:23:33 and then I arrive to this webpage:

http://data.guix.gnu.org/revision/b023a8acd38b57b159aeeef0ac6de73960f97e8b/package/git/2.26.2

Nice! All green!! :-)


Another example, I am going to this webpage [1]:

[1] https://data.guix.gnu.org/repository/1/branch/master/package/docker

and say I click to (More information) below 2020-05-06 16:18:16 and
then I arrive to this webpage:

https://data.guix.gnu.org/revision/758f32afdbc6cf6018a2e76eef5085f6b693c15a/package/docker/19.03.7

Bad news! Docker is broken.  Going back to [1], now I try another
(More Information) until I find one green.


Well, to avoid to click, I would like to have the red icon (X) or the
green icon (V) close to (More information) to easily visualize which
ones I want to click.

Hope it makes sense?

Cool!  Thank you for the tip.  I will give a look.

For people in paranoid mode? ;-)
