The "work" feeling of vertical text

I'm grateful that so many people find it interesting that I can now write a diary. So I took the opportunity to make it possible to generate PDFs today. You can create Japanese and Traditional Chinese in vertical writing, and English and Hangul in horizontal writing. The generated PDFs are in a format that can be submitted to various printing services and include crop marks and such, but since there's no cover, they aren't really complete yet. Sorry. When I look at the PDF formatted in vertical writing, it looks like a proper 'piece' — different from how it appears on the screen — so the vertical-writing effect is surprisingly powerful. (laughs) However, the underlying process is heavy and it inevitably takes some time. I don't think it takes as long as five minutes, but five minutes on the web can feel almost like an eternity. Therefore, I've set it to send an email when creation is finished. I'd like to work a bit harder to make that faster. I'll keep improving it little by little.
