Progress Bar for uploading
I really down understand, why actually no browser has a descent progress bar for uploading. When uploading a huge file via HTTP POST in a Form all you get is exactly nothing. Sometimes a upload can take a while, esspecially, when the upstream is low. So uploading a 2MB file or even bigger in a CMS System gives you no response during that time.A small upload progress in the middle of the page would be fine, when the upload lasts more than a few seconds, maybe show it after 10 seconds or so.

PS: Besides: Awesome browser
It's there already (almost) - set progressbar to pop up at bottom of window. It doesn't show percentage uploaded, but shows speed and time elapsed.
Actually current progress bar shows speed, elapsed time and approximately shows size of uploaded part (32, 64, 96, 128K etc). Frankly speaking I don't think it is technically possible to determine exactly what part of file actually reached remote server in the moment (am I wrong?), but if not technical issues it would be nice feature.

AFAIK it's one of basis rules about TCP/IP.

I monitor that status bar too, still it doesn't provide that much info. Adding to tis idea, the tranfers section could have a split section to show current uploads with all sorts of technical details (Speed, Server, IP etc).

I really wish to be wrong, as I also want this feature. But consider:
You meant sent to nearest intermediary/proxy, not origin server
Received by nearest proxy?

I don't know how works sending files by proxy.
But just imagine - how transfering could works in case Opera don't know which part of file should send?
I think Opera sends first packet, waits for confirmation and then sends next one. Like any other programm using TCP/IP.

Brilliant idea, especially for us dialup users!
All non-naive TCP/IP implementations use a sliding window to increase throughput, but this is essentially how it works. Also, IIRC, if a proxy stops receiving ACKs from the server, it stops sending them back to the client, since proxy servers (generally) do not store content.

this feature will be very useful...
But the progress bar should pop-up at the bottom of the page. An it should be also in Transfer panel... with red background for uploaded file lines and green background for lines showing downloaded files...

Program has to knwo which part of file should sent atm.
Well, the program is not responsible for controlling the connection. Opera just chucks all the data to WinSock (or another OS equivelant), and Winsock + the TCP/IP drivers decide how to send it. Basically, the program writes the data to a buffer, and then Winsock gets the data from the buffer and send it. Opera doesn't actually know the exact amount that has been sent (at least, that's how I think it works)
Receiving is a different story. Opera knows exactly how much it has received, as it is reading all the data into an internal buffer/cache. Opera knows the exact size of the buffer and its contents.
Anyway, I don't think that this feature is really needed. The status bar's estimation is OK (the estimation it makes is based on how much it has written to the buffer, I think), just check the size of the file, and compare it to what the status bar says has been sent

I can't imagine why anyone would not want to have a progress bar for uploading files. Usually when I try uploading an attachment to my mail server, on a machine where I don't have M2 set up, I often get the impression that nothing is happening at all, so I retry the upload - possibly stupid, but human. One of the elementary things to learn about HCI.

I love this idea, not only that but I wish that Opera would upload as fast as IE, I don't know if this has something to do with IE being more shell integrated or something, but usually IE uploads 3x faster than Opera, yet downloads like 3x slower than Opera, *laughs*. +1

Wish list:
- show transfer panel when starting a download
- make From field in "compose mail" editable (maybe depending on a opera:config setting?)
