Currently, the page looks like this.

Potential issues to address:

• Widen out and space the elements clearly
• Easier accessibility for the month/year input
• Add sorting to table columns

I wonder if people most commonly want to see cross-Wikisource stats, or stats for just one Wikisource? Of course, both are useful, but I feel like a single-Wikisource chart of numbers of exports over time would be useful, as well as a list of the last month's most popular.

Perhaps we need more than one page of stats, with a navigation at the top? That'd help by also not having to run the expensive queries all together (although we can also add much more caching to the queries too, which will help).

Made a PR here

Also, I feel like adding separate stat pages for the individual language wikisources should be done in a separate patch as it would involve more querying changes as well.
