Progress meter only make sense Tal, if you have a solid information of the end of your action. Example: you asked for a file, and you know in the beginning that it's a 100mbb file. Than you can do a progress meter. The spinning or a progress bar animated(but with no real meaning to the state of the bar.. the famous animated bar) is the same thing we just choose the simpler visually speaking.

So, twonky if it's sending small pieces, doesn't tell us how much lists there are there. Giving user feeedback (meaninful) it's a personal dream (as designer) but not always possible : / and the worst (sometimes is not related to canola -but there are a couple of places where we will improve it)
