Since the dictionary works as a pop-up on any selectable text, then if I look up a word and there's a "see other word", there is no way to jump to the next word. If the definition contains a word I don't understand, there is no way to click through to that word.
This is the dictionary I'd like to see on my phone.
There are a lot of dictionary apps out there but I think most developers miss the forest for the trees. I don't know why there's still not a single dictionary app that is blazing fast, use the built-in dictionary and have some common sense design choices (literally not came across a single dictionary app that doesn't enable keyboard as soon as you open it -- it's a dictionary app, why do they think I open the app?!).
Kotoba (https://github.com/willhains/Kotoba) is almost perfect but there's no way to download it from the App Store and I don't want to deal with the hassle of sideloading on iOS as a non-developer.
It has the added benefit of being integrated with the system dictionary, so if you add any extra dictionaries to the system, such as foreign languages, they will also be immediately supported in Kotoba.
Unfortunately: "App Store guidelines disallow using the built-in system dictionary to create a dictionary app"
