| Good morning. We hope you had an enjoyable Easter that was not spoiled by President Donald Trump's profanity-laden message. As you perhaps read yesterday on our pages, we looked at the meaning of the season quite differently. Today, the editorial board takes a look at the new regulations surrounding so-called accessory dwelling units, sometimes called coach houses or granny flats. We are glad to see the loosening of the rules surrounding their construction, but we'd like to see fewer rules governing how they can be used. We also took a look at the flap over at the Chicago Housing Authority, where Mayor Brandon Johnson has not been able to install his preferred candidate to run the operation, affecting the dwellings of thousands of Chicagoans. We see this as a good thing, frankly. Given the perennial chaos at City Hall, we think the so-called sister agencies (such as the CHA, the CTA and the Chicago Park District) have to become far more independent if they are to serve their constituents. Taxes are coming due. So you might be especially interested in our editorial on the size of your potential tax refund! Let me also highlight what I think are some "must-reads" in our Tribune Opinion section for you this morning, starting with the latest piece from Pegah Banihashemi who has become something of a regular contributor for us, giving our readers her exclusive insights into the Iran war from the perspectives of the Iranian people. This weekend also saw the second installment of our Chicago 2050 series with a piece imagining the future of our transportation system and also a contribution from Daniel Holz, a professor of physics at the University of Chicago who studies black holes, at least when he is not writing for us about progress and avoiding doomsday scenarios. Also our architecture columnist Edward Keegan writes about the new computer science building at the University of Illinois at Chicago, a creation he calls "willfully eccentric." He means that in a good way. Check out what he has to say and the rest of our offerings below. And, as always, we have lots of your letters to share. — Chris Jones, editorial page editor Submit an op-ed | Submit a letter to the editor | Meet the Tribune Editorial Board | Subscribe to this newsletter |
