This suggestion is an aesthetic aspect, but I think love for details is also important.
Currently, the titles of the posts have a maximum size of 255 characters, however, the URL only display 80 characters. When a long title is written in a thread if the last character (before the limit) is a space is also displayed in the URL.
I think it would be nice eliminate that last space in URL. As I said, it's something aesthetic, but it is a way to improve the aesthetics of the software.
It’s more beautiful, don't you think?
