Japanese crossword «Kitten»

When I go to mark a number, on the large puzzles I lose track of what column and row it is. Can the highlights extend across the entire puzzle?
The captcha number always expires when I'm typing. Can you increase the time?

Cute!

Definitely cute, and keeps you busy for a while. My problem is that I use a desktop pc, so the tall puzzles are a bit annoying as I have to keep scrolling up and down, from the bottom squares to the number bar at the top (even when using micro).

Good
