Hello, I think it would be interesting to be able to see statistics for a wiki project (Wikipedia, Wikisource, Wiktionary, ...) for all language versions at the same time. That's mean that if I select Wikipedia alone (and not any language version after), Wikistats will display the statistics for the sum of all the language version (en + de + fr + es + ...).

Adding some context from @Varnent. Comms uses these kinds of metrics often, see the full details here: https://office.wikimedia.org/wiki/Communications/Guidelines#Statistics. And fun fact, the original Wikistats uses project code "ZZ" to indicate "all", so zz.wikipedia means all wikipedias: https://stats.wikimedia.org/EN/TablesWikipediaZZ.htm
