Let us be able to seek +30 seconds instead of to next nearest 30 seconds interval

Describe the feature you'd like

Currently, when skipping ahead, the client always skips to the next nearest 30 seconds interval, making it skip anywhere from 1 second to 29 seconds ahead. This is unpredictable and not really useful. Intros are often 30 seconds and using this skip method, you are almost guaranteed to never be able to skip exactly ahead 30 seconds.

I suggest to simply skip ahead 30 seconds. This is predictable and useful.
