For those that want to vote against any kind of chatfunction in µTorrent, you can now vote here. Keep it simple, keep it small and keep it quiet.

Title says it all. When I load a page with Opera, for example, utorrent limits it's bandwidth. When my page is fully loaded and I'm reading it - utorrent is back to full speed.

I think it would be very good if programmers were able to write plugins for uTorrent, just the way they do for Firefox.
This way it would help uTorrent to grow very much.

make a searching by torrent's name in the uTorrent torrents grid.
just, when you have about 100 torrents with a similar names in the grid, searching torrent's name which i need, requires some time.
it would be nice to call this function by hitting "Ctrl + F"

Add streaming support!

When i downloading torrent and there is for example 100 files, i can set priority to first file high and second normal and all other files have low priority.So it will be downloading in order -first file, second file and all the rest.

It would be good to make more priories for files like queue for torrents.
For example i am downloading torrent with 100 files and set order of files - first whole file _01.avi, after downloaded _01.avi download 02.avi, later 03.avi and so on and not how it is now - part of every file.

i.e. MB to MiB which is the correct one
1 kB = 1000 B
1 KiB = 1024 B
also transfer rate (if used!)
1 kbps = 1000 bps

1 label is not enough some time. More needed if possible.

Use GetLastInputInfo to build an inactivity detector, stop all downloads and uploads while the computer is active. Provide an option (default off).

I like to group my files in specific locations, so it would be nice if we could move data files to different file/HD locations, especially if HD space is running out

Add a setting to globally set a program to run when a torrent completes. Currently this option is only available on a per-torrent basis. It isn't always possible to manually set a program for each and every torrent added, especially if you have uTorrent automatically loading torrent from a set directory.

Using "labels" detect pre-entered keywords to automaticly apply the label coresponding.

this way when downloading series on weekley basis torrents would set their own label automaticly!

Instead of having to wait for the entire movie/album to download only to find out that it's a fake or in a language you don't understand, it should be possible to preview the files.

This means that uTorrent would create a short watchable/listenable/readable preview of what's being downloaded (from the beginning, so that it wouldn't be a spoiler) for the user to see if it's what she bargained for

Make a native Windows Home Server addin/plugin allowing users to manage their torents from a Windows Home Server Console.
This is a third-party one but it is no longer being developed. A native addin or even complete new uTorrent for Home Server would be terrific.

When user downloads a torrent, after testing or running it user could rate it.

when a user downloading a 'rated bad' torrent then utorrent shows a warning about bad torrent (like azurious)

uTorrent should save computer id (hardware id) when saving rates to ensure that one user rates only one time for a torrent.

Since ordinary .torrent files have this by default, magnet links should behave like this. It is pretty desirable for persons who don't want to download wholly a torrent, but want to get just some files from it.

Add the ability to unrar and/or move files using only µTorrent on completion.
