The way it is now, it is compleltely useless. If I change a word, or a letter, it marks the whole passage, or at least the whole sentence, so it is impossible to spot easily where the change was done. At Wikipedia, they use different tones of two colors. Lighter tone for the whole pasage, and darker ton for the each word or a character that was changed. This imake the spotting of the changes easy, and I wish something similar would be implemented here.
On the other hand, I would also like to have a link to click ant to go to the next chanbge, instrad of scrolling down again, marking next two changes etc, It is boring, slow and unefficient.
Pleeeeeeeeeeeeeeeeeeeeeease. Fulfil me my wish! Quickly! :):P
