Would it be possible to replace the core TW5 story river with a tile-based variant, including kind of a responsive design? Where tiddlers would be the individual tiles, rendered side-by-side first, then top to bottom. I'm trying to figure out if I can turn TW5 into a poor man's portal page presenting videos to users, where the tiddlers have embedded video players, and the tiddlers can be filtered by certain criteria, etc. Any suggestions as to how such a tile-based story view could be done?
