@wbazant Neat idea to bring over some of that functionality.

There seems to be issues with keys that accept parameters or that contain raw HTML. Their value (in the former) or their key (in the latter) is "[object Object]", and in the latter for some reason the dialogue and message are different on click.

In terms of implementation, something that might help is that passing language 'cimode' to the i18next library exposes the key rather than the value (see https://www.i18next.com/overview/api#changelanguage). Unfortunately, in the current version of Phrase, it isn't possible to build a URL to the key in the translation editor from the locale and key (instead you need to know the internal Phrase id of the locale and key).

Finally, it's worth mentioning that Phrase provides adapters for an in-context editor: https://support.phrase.com/hc/en-us/articles/5784095916188-In-Context-Editor-Strings
We have a paid plan for the next year, but based on the pricing and my communication with them about the surprise payment, I'm not sure I want to invest too much in their platform (i.e. we may want to jump ship).

Thanks, I thought it'll be handy when we start doing the translations.

accept parameters
Added a hack - the issue was with keys that accept other translations as keys. I've rendered them as "[1 day] ago" , where the value in squares is an example for that entry.

raw HTML
I did something different there because toast() doesn't work when stringified and re-parsed, but alert() of a simple string does. I also noticed that it needed fixing for i18n_viz=keys, because it showed up badly.

I'm with you on not potentially staying with Phrase - I was thinking to implement a process with Google Sheets as UI, where a script produces a spreadsheet, we upload it, and then merge and review changes. It won't have Phrase features that people working with professional translators want, but it could be easier to contribute to: instead of a "let me add you to Phrase" step, anyone can just start. Also, no tempting 'AI translate' button from Phrase.
