The current implementation of URL recognition could be improved.
First, a lot of times textra cannot correctly identify when the URL actually ends. It often includes the comma or period in the end of URL, and in Chinese, there is no space in between sentences, because period in Chinese are twice the size, so you would not need an extra space to separate sentences, that is a problem since textra would not figure out when URL actually ends because there is not space.
Second, I think when tapping on URL, a pop up window that lets you choose whether you want to open the URL or simply copy the URL into clipboard would be super helpful!
