[IMPROVEMENT] Allow user to switch between previous/next comment on timeline on scroll events

[S-trace]

Hello.

It can be handy if the user can switch between previous/next comments using scroll events (vertical scroll or horizontal scroll). because some videos can have many comments in a short timeframe, and it is difficult to target the next mark even on regular videos in the current implementation.

Thank you.

I mean not to change the playback position to the position marked in a comment, but to switch between comments on the timeline.
Comments may have very close markers, which require very precise mouse positioning to read the next comment and is annoying. Using the scroll wheel to show previous/next comment text (if the user hovers the mouse over one of the comments marks on the timeline) can make this extension better, I think.

I have recorded a screencast for this issue.
Please take a look at it - to view the next comment on the timeline I need to move my mouse very precisely, which is not comfortable.

I have paused YouTube to show you only the effect I mentioned (and I had to reduce my mouse DPI to poison my mouse (I usually use 1000DPI precision, but reduced it to 400DPI for this,

I think it may be useful to allow users to use mouse scroll events instead of cursor movement to switch previous/next comments (and even previous/next comments at all videos but not just around mouse pointer) without changing playback position.

Video can't be played because the file is corrupt.

Unfortunately I couldn't watch the video, but I understand the issue.

I played with a scroll events a little bit. I decided to use vertical scroll to scroll long comments (it's already in the master but haven't released yet; see a0fac77). I'm not sure about UX of comments switching. Are you ok with horizontal scrolling for it?

UPD: version 0.5.2 is released.

Are you ok with horizontal scrolling for it?

Yes, using a horizontal scroll will be very intuitive in this context.
Thank you!
