"I really need the color setting for download speed. It's really useful when i can see when there's a problem."
I believe he is requesting the ability to define Fast, Medium and Slow download speed ranges, with each range associated with a different colour in the download bar (eg. green, orange and red). You could define Fast as > xx KB/s, Slow as < yy KB/s and Medium as in between the two (the speeds would be user configurable). Hope that helps.
