I submitted version 1.1 to review.
Includes a mode (enabled by default) that lets you see many comments on the screen at once.

1.1 is a hotfix that had to be published quickly because of the screenshot #6.
It was my mistake, I should have looked closer at the content.

Version 1.2 will have donguri capability, BE capability (the api is almost finished), improved AA rendering, and more convenience.
