Window sync is broken, my latest changes in terms of pinned tabs and folder creation was deleted because theyr'e weren't on the latest closed window. Zen remembers and saves the last closed window status, even if you add changes in other windows. I really want to migrate to zen but Arc is solid.

I was waiting for this feature tbh. There's a GUI bug on macOS Sequoia latest version, window spheres buttons are smaller than the mask on the windows, maybe is optimized for Tahoe not Sequoia.

There's some bugs with tab titles not updating whose fix after relaunching the app.
