Thanks, it's great to hear you like the app! :)
Thanks, I'll consider it. Chmod is also a command that's missing from the ftp client.

Currently, you have to download the files and upload them again to move them to a different folder on the server.
Adding custom syntax definitions will be added in Textastic 3.0.
If you use this website from your iPad, you have to tap once on the vote box and then once again on the arrow on the top of it to cast your vote. If you use it from a computer, you can simple hover over the vote box and click on the up arrow.
I plan to support this in Textastic 3.0.
I'm not sure what you mean. Textastic doesn't convert spaces to tabs automatically.
If it was easy to fix I would implement it correctly. But right now, all the calculations for drawing and cursor positioning etc. in the editor control are based on the assumption that every character has the same width. I would basically have to rewrite the editor to use CoreText for drawing and coordinate calculation if I wanted to support all unicode characters and unicode characteristics. I think this would make everything much slower.

I didn't really expect it would become popular in Japan :)
I improved the Japanese character display in Textastic 2.2 - it uses the same height as the western characters but 68% of the width so it's much more readable. I will submit this update to Apple soon. This is similar in effect to the workaround for TextMate described here: http://blog.macromates.com/2006/faking-cjk-support/
