I suggest to change the PR title to make it clear it's about the docs.

I'm -1 on this. .po files are not very friendly for reading by people, and are designed as a translation format mapping source to translated strings. I similarly see little value in 'show source', as the reStructuredText source is so unlikely to be useful (some themes have replaced this with a link to the source on GitHub, but I'm still unconvinced).

I often use "show source" when I want to check, well, the source, for example if there's something amiss.

If there's a translation that's missing or fixing, is the .po file the file that needs editing? If so, this would make it easy to click through and make a quick PR.

Hugo already mentioned the main point.

Another thing is the current „show source” button is useless in the translations as it is the English source.

This will contributions as it is easy to find where the files are as the repo is not linked anywhere else in the docs!

And also, Adam, you don’t have to worry about seeing it :-)
