Do we have an idea of what the average number of languages people will have enabled? 

A. feels a little risky assuming there is a long-tail of languages enabled
B. doesn't feel helpful

A possible "C" option is showing: 
"English (United States), Spanish (Spain), and [x] others"

The first two languages can be the top two preferred based on the order of them in the subpage, and then we handle the overflow with just "and [x] other" for one, and "and [x] others" for more than one. 

Thoughts?

+rouslan@ who worked on multilingual spellcheck. Rouslan, do we have any number on "average number of languages"?

We never got around to measuring this number. In general it is believed that ~50% of users are multilingual. Does that help?

Alan's "C" proposal in #1 seems fine to me. I don't think users can reorder their spellcheck languages, but if they have more than 2 it doesn't seem critical to show the "top" languages.

In the old settings UI, the order of languages also specifies user's preferred website languages, where order matters. Does the new settings UI behave differently?

There are different sections in MD Settings for "Language" and for "Spell check". My understanding is that the Language section can be reordered, while the Spell check section cannot.

Looks good!

LGTM. Thanks! 

so, WebUI doesn't have great tools for translating plurals

we're using 4 string formats:

* "Lang1"
* "Lang1, Lang2"
* "Lang1, Lang2, and 1 other"
* "Lang1, Lang2, and N others"

It's not terrible, but it will be awkward in some languages which have different pluralities (e.g., a different suffix for "2 others" vs. "3 others").


jungshik suggested:

* "Lang1"     
* "Lang1 and Lang2"
* "Lang1, Lang2, ...  (total: N)"

IMO that's more awkward in general, but would be easier to get right for languages with different plural numbers.

@michaelpg, is this done?

I'd honestly be fine with just indicating that there are more, eg:
- "Lang1, Lang2, ..."
- "Includes Lang1, Lang2, Lang3"
- "Lang1, Lang2, and others"
