Well well, things they are a changing (hit refresh on your browser!)
Desktop view has been updated in the core engine to be a lot more compact. The upside of this is that there is more room for titles without having a new line. The downside is there is now a lot of unused central space and the font appears a little smaller - select Theme “Larger Fonts” or “Extra Creamy” on the Hamburger menu if you want to compensate for that instantly.
I may experiment with new layout to better use the increased space.
One option is to change the default view for Desktop to Category view (from Latest).
Another option might be to use the extra space for a sidebar …
