Today I decided to spend some time improving the website for the Stacks project, fixing bugs and implementing some small improvements. I grouped the issues in the GitHub issue tracker that I wanted to address. Here are two highlights, not because the bugfix was interesting, but because you might learn something about how to use the website.
the search now works better with quotes: If you want to learn about quasicoherent sheaves in the Stacks project, you should first of all know that the spelling quasi-coherent is used. Then it is important to know that if you want to use the search function to find results about quasi-coherent sheaves, you should enclose it with quotes. I.e. the following would be a way of looking for tags mentioning quasi-coherent sheaves on a stack:
Because of a silly implementation mistake by yours truly, the search would be successful, but the keywords would disappear from the search field. This is now fixed.
the captcha is now easier to read: I love it when you can make something better by such a little change. We are now using a font that distinguishes between '0' and 'O to display the tag identifier. This was a nice idea by Brian Conrad, thanks!
The other bugs are not very interesting, and most of them had a nearly trivial fix anyway.
