I hear what you are saying and this makes me sad for two reasons: first of all, because it makes it pointless to have an Envato community if Envato doesn’t weigh in the conversations over here; second, because I saw that you removed your post right after reading this one.
I must say, though, that there could be something regarding your idea that justifies Envato’s reply (“I can’t promise anything”) and prevents them from integrating it in the system. What if one track of yours has already sold 1000 licenses and accumulateld 5000 downloads but, while they kept tracks of the former, they never thought of storing somewhere the count for the latter? Well, as soon as they start counting the downloads, if they never did it before, you would have 1000 for the licenses and 0 for the downloads, which is going to be pretty confusing and misleading. Or you could have 1000 for both as a starting point… but even that is pretty meaningless. That is why I can see why they could have some second thoughts regarding your idea.
Don’t get me wrong! I completely support your idea and I don’t know why they did not even of it in the first place. Even the player I am selling on CodeCanyon does that on every track: as soon as you click on the download button, the counter increases like a “Facebook Like” button does, with the visual feedback of the total number of downloads.
But if they never kept track of the downloads, starting now would create a discrepancy between what you see and what is real, that you will never know anyway. I hope this makes sense.
