Feature description

Ability to add multiple timestamp to a video without fiction when watching in full screen or floating window.
Not having to enter any title just like a bookmark button or swipe gesture to record timestamps multiple times on a video and store info with specific video.
Ability to export these time stamps to clipboard after watching the video.
Optional clickable links if possible to navigate to these timestamps would be nice but not necessary as purpose is mainly to export to clipboard for adding to other note apps.

Why do you want this feature?

Youtube now has become a source of instant, diverse and updated information.
To eliminate friction in processing these videos on the fly. This feature request addresses this by not worrying about remembering the time stamps of portions that are of interest is a stress free and huge time-saving solution. It also compliments the app use case for this purpose.
With the ability to export these timestams of a specific video to clipboard, allows the user to save this on any notes app of their choice for further processing and can be addon to their existing workflows.
Does save time for user, also productivity aspect would encourage more use of app as it would be unique to Android. There are chrome extensions that do this already on desktop browsers.

Additional information

I would be more than happy to help with placement of button/swipe gesture and provide feedback on ui experience

[offbeat-stuff]

This seems way too extra of a feature. Seems good in retrospect but is too niche to be used by most people. Could lead to bloat and other bad code/ui pattern that newpipe is trying to avoid. Otherwise nice fr.
