In the Categories page, I have setup many categories and I need to quickly check which ones are already there or if there are any duplicates with similar names.

I used Ctrl+F to search category by text, but it doesn't find text inside the table (esp. the Display Name column), making it harder to be sure about existing categories. There is no integrated filter/search field either.

So I have to either manually check each category or try to create a new lone until they warn me that a category with the same name already exists (and that doesn't work to detect categories with similar, but different names). Or I must finish arranging all the categories in all the groups and then check for duplicates in each group. But I'd rather do it on the go.
