[wishlist] ability to filter / search in stream

[axx]

Right now, as far as I can tell, Gwibber lacks the ability to search in streams.
Sometimes, I just want to go back to an item I glanced over in my stream but I don't want to have to look around in the stream to find it.

If we could filter the streams or just search them, a bit like one can search in page on Firefox, it would be great.

Furthermore, a search function already exists, but it will search all of Twitter or Identi.ca and not the personal stream, and create a new stream for the results, which is not what we want here.

Thanks!
