I've noticed lots of mismatching frame numbers between koohii and RTK1 6th ed, and usually when adding a new block of kanji I have to look up the ones that are missing manually. That's manageable, but now I've run into a kanji that has a completely different keyword on the site to the book. In RTK1 6th ed, 填 is "inlay", frame #166. On koohii it's "stuff up", frame #2190. Which edition is this website using, and is it ever going to be updated fully to 6th ed.?

See the 6th Edition Frame Number Converter sticky...

I know I can use that resource, but it doesn't answer my question.

It uses the 5th edition.

ps: Yes, some characters in 6th edition have had their keywords updated in order to accomodate the kanji that were added from the previous RTK Supplement and I think some from RTK Volume 3 that were moved to Volume 1. There's very few of them though, there is a spreadsheet somewhere in the stickies comparing the editions.

In the case of keyword change you can edit the keyword on the site, but the search box does not currently use the custom keywords.
