System and IINA version:

• macOS 10.12.3
• IINA 0.0.6

Expected behavior:

Users might press 'v' by mistake, but there is no explicit signal to tell users how to fix the unshown subtitles problem if they don't read this config [https://github.com/lhc70000/iina/blob/master/iina/config/iina-default-input.conf].

So I think explicit show the sub-visibility in the subtitles menu will enhance the user experience.
