It would be nice if Kagi News supported furigana for Japan news. Kagi Translate for example already supports furigana.
This would be a pretty nice feature in conjunction with the ability to simplify a language to Simple or Very Simple, which already have language learners in mind; reading the news tends to be a convenient way to practice reading, and furigana helps when encountering an unknown and/or complicated set of kanji.
Perhaps having a simple checkbox to enable/disable furigana in the settings and/or alongside the options to simplify language.
The NHK Easy News site for example provides full furigana since it is meant to be an easy way to read the news.
If implemented in a similar way it would also work with things like userscripts that hide furigana based on one's progress on various learning websites for maximum practice.
