Just released v.0.0.18 which provides the functionality you are looking for (as far as I can tell). Please give it a shot.
Please note that the page icon’s feature to fuse tiddlers in the story river is not shown by default, but can be enabled by turning on the relevant setting under Control panel → Streams settings → Configuration → Streams-fusion: Show page icon. The default filter for this feature is to fuse only Stream tiddlers present in the story river, as requested, but the filter can be customized to something else.
@saqimtiaz : I have had to tweak (and sadly package along again) the $:/plugins/sq/streams/Settings/config tiddler to insert [[$:/config/PageControlButtons/Visibility/$:/plugins/phiv/streams-fusion/ui/page-button]] in the list filter so that the page icon visibility setting is also shown on the configuration page (which I think makes sense). Not ideal to override the original $:/plugins/sq/streams/Settings/config tiddler, and I tried various forms of transclusion to have the visibility setting included there, but did not succeed. Inserting instead a more generic filter run would probably make more sense, e.g. a Streams config tag in addition to the prefix-based filter run, as it would be more flexible than my current approach. Happy to converge, as you see fit, in future releases of this $:/plugins/sq/streams/Settings/config tiddler.
