Hi Djamileh
Thank you for your question. At this stage, there is no immediate plan to pull the user tours out of the experimental features section, sorry.
This feature is not fully supported in the new 'TUI-based' pages in the Talent Experience Platform, like: centralised notifications, Engage library pages, workspaces, playlists, Perform pages.
There is no immediate plan to build more support for user tours in this area, so it is being retained as experimental only.
Hope this helps give more context. I'll talk to the team about getting the documentation in https://totara.help/docs/what-is-a-user-tour updated to speak to this in more detail.
Thanks
Bryn
