Thanks for the quick reply, Suicidal_orange! (and my first reply too)
Yes those arrow keys was the deal breaker for the typical 60% layout. After talking to some of my friends who's been in the custom keyboard game for some time now, those arrows are quite important.
In the long term I'm also seeing if I could make a keyboard case for the 65% layout. The focus would be wood, doesn't seem like there's much out there for wooden keyboard cases in comparison to its aluminium and plastic cousins.
