We use Trello, Lighthouse, Zendesk and Pivotal Tracker. We hook them all into one stream with www.hojoki.com. This helps us search between them all and discuss what's going on.
That can be challenging if you have a lot going on. You can use tags and then sort by tags using the search. You should just use the search where you can to narrow down your results until you find exactly what you want.
yea I just tried it out by hooking trello to it. It's good that it pulls in all the feeds from most apps. Makes it very easy to see whats going on. Like a live twitter feed! But hard to manage the focus, will try search and tag
