Hey Chuck. I started using Arc in January and haven’t looked back since, it’s always jarring having to go to another OS and not have it available. It’s been fascinating and refreshing to watch their journey and how they are so open about everything they are doing.
Anyway, if you want to see the URL all the time then you can show the toolbar (SHIFT+CMD+D)
Also, with regards to shortcuts, you can specify in settings/preferences whether you want the Arc shortcut or website shortcut to take priority (find the specific shortcut and there is a drop-down on the right.)
