Seems like it. I suppose it’s an honest mistake to make, she (or her PR team) put the Kanji for “seven” and “ring” (but also more generally means circular or loop or wheel), but Kanji when combined doesn’t always mean what you’d expect it to mean. In this case those two Kanji together is a noun meaning charcoal grill. Kanji combinations can be highly logical, where their standalone meanings come together to a very sensible combined meaning. But sometimes they don’t make much sense and the reasoning for the combined meaning is lost to time.
But come on, man… Just search for it online or open a dictionary before you permanently write something on your body.
It’s a bit hacky but I suppose there’s always the option of using a separate WebDAV server on the directory where frappe drive stores its files. I haven’t tried something like that, though. Unfortunately I don’t know of any integration within frappe drive itself. Seems they’re accepting contributions now so it’s possible these will be implemented in the future. WebDAV is a bit of its own beast, though, so that’ll be a huge undertaking in my opinion.
