Styling issue on preview button with the Japanese locale

[mayukojpn]

Hi, thanks for the great plugin! We are enjoying it :)

I found a button styling issue after we translated the plugin to Japanese.
The last text overflowed from the screen.

I also suggest changing the texts along their contexts:

• Animate block -> Preview
• Animate all blocks -> Preview all

Updated the plugin, UI changed significantly in the latest version (1.1.0). The overflow should no longer be an issue. Let me know if everything is good in Japanese. Simplified some strings as well, some may need to be translated again unfortunately.
