Ok, this is an extremely minor thing… But I've noticed that the "Search with…" and "Look up" items are in the opposite order in Orion than in Safari 🙂 and I end up clicking Look Up when I want to search and I go "WTF?!" when I don't get what I wanted, because it's just muscle memory and I click it without thinking… I guess it would make more sense to have it the same way as in Safari.
Also "Speech" could also go right below "Share" too? But probably not used nearly as much.
