is twalala my solution for twitter filtering?

I love Twitter, but because my primary use of it is to keep up on the day-to-day lives of my friends, I don't like reading "live tweets" of events. They tend to create a flood-like effect in my stream of updates that drown out the personal things I care about.

I can always unfollow someone who does that a lot, but often they're people that I really like and care about and want to follow. So I've been looking for something that would allow me to hide only their tweets on specific topics (typically those that contain an event-specific hash tag, like #etech).

It looks as though Twalala may do what I want. Here's what the filter options look like:

The only downside is that I usually check Twitter on my computer, and Twalala is obviously designed for use on an iPhone screen. I'm wondering if there's a way to add a user-defined stylesheet so that I can get the Twalala filtering goodness in a full-size-browser-friendly format...
