+Three things this month:
+1. We've updated the UI for iPadOS 18 – no more tab bar, everything is navigation-based, which should be a better use of the larger screen size.
+2. Some iOS 18 improvements – a few color tweaks, some bugfixes, and most importantly – tintable icons!
+3. We've been hard at work on an experimental new block editor. It's not ready for full-time use, but we'd love your feedback! Check it out in Me > App Settings > Experimental Features.
+If you have feedback on any of these features, we'd love to hear it – reach out to us at [email protected]!
