Limit the number of words / sentences shown per page
I find it overwhelming when I see a wall of text in a foreign language before my eyes. I propose to limit the number of words shown per page to help users manage this anxiety.
I saw this feature implemented by LingQ: they would allow you pick if you want to see a sentence or a paragraph per page.
I would suggest implementing the same feature here (and I like this service way more anyway)
All the best!
