I want to open a permalink

[manuroe]

We need to be able to back and forward paginate from a timeline created from an event id.

If the event is already in the local cache, we can navigate from it and continue to fill the cache.

If not, the timeline data can be only in memory like on iOS and on android sdks. Note that we tried to cache that data on android with some mechanism to merge continuous timeline but we disabled it for DB performance reasons.
