Infinite scroll in both directions (i.e. bi-directional endless scroll)

[lightsound]

Hi,

I need to implement a chat like Slack. When we jump to a particular post in Slack, then we can scroll endlessly in both directions.

I am trying with virtuoso, but having trouble adding data. If one direction works, the other is not working. I looked for past issues and discussions but could not find them. I would like to know how to implement this.

But anyway, thanks for the awesome library.
