Xodo's Android version has a built-in online dictionary which is very useful, especially for students. If the same could be made available in the Windows version it would be amazing.
I am someone who reads a lot of books in pdf. And that also means I search the meaning for new words every time I come across one. And doing this by opening the browser or phone dictionary every single time is a pain. I would love to read on my laptop as it obviously has a bigger screen. But the only thing stopping me from using the Xodo's Windows version is that I can't use the built-in dictionary which is available in the Android version. So I have to make do with reading on my phone even if it means the texts are smaller, just so I can use the dictionary. Making the built-in dictionary available in the Windows version would be really helpful.
