Hi Professor Ann Loraine
I just noticed that we are showing _ in the edit page while tagging a App with a particular category. That is a small detail which was missed (can be changed to not show _ on the front end), in the backend, yes we need _ character for spaces because it breaks some hyperlinks for space.
Can we create a ticket to check what breaks when we do spaces instead of _. I remember adding that as there was something that broke because of the space.
Sai Supreeth Segu : This ticket needs more work as with your change the subcategories will start having _ in them, titlemodified is a template filter which removes _ from the string.
