Bookmarks in Session replay

[lukpanek]

Feature request

Hi everyone! My first feature request, so sorry if something's missing or is incorrect. ❤️ Trying really hard! Thanks for all your work, love your product! 🦔

Is your feature request related to a problem?

I don't think it's a problem – nothing is broken or all that annoying. Just an improvement.

Describe the solution you'd like

Have an option to add bookmarks to session replays. Clicking on a button next to the recording creates a bookmark at the current timestamp. A little view to show a list of bookmarks would be helpful, or/also show them on the timeline. Something like in video editors. Have an option to filter replays with bookmarks.

Describe alternatives you've considered

Until now we're placing all the recordings that interest us into one notebook with additional description and timestamps. That's a great solution – it helps a lot for providing additional context when passing feedback between team members. But it lacks the ease of use of something like bookmarks.

Additional context

We have a lot of recordings to go thru to catch errors from our beta-testers. Placing individual recordings and timestamps into notebooks is time consuming and performance struggles (it autoplays a lot of recordings, so it lags a lot).

hey thanks @lukpanek

so I can see you've spotted how to comment on timestamps in notebooks
you can share recordings to playback at specific timestamps ( in case that's helpful)

but I guess that's not the same as you'd like to place an arbitrary number of bookmarks

interestingly posthog already has annotations which can be placed on insight timelines 🤔

do you have any example UI of other tools you've used? or expectations of the types of interactions you'd like?
