We currently do not have a feature to simply enable for continuous horizontal navigation. We’ve added the feature to our backlog to be worked on in the future. We don’t have a timeline for when it will be available but if it does get worked on we’ll let you know when it’s available in an experimental build to test out and the estimated official release date.
If this is a critical improvement for you, and you need a fixed timeline for this to be completed by, then the next step would be to do a paid custom engineering project. If you are interested in that, please fill in this form.
