With over 1000 torrents in a list, it can be cumbersome to sort by name in order to find a torrent with a given title in the main window (or if the keyword in question is not at the beginning, often impossible).

The main window should include an explorer- or finder- style list keyword filter, or a firefox- style find bar, or at the very least a find dialog box.

Some trackers are always well seeded and require (and allow for) less upload. I usually lower the ratio goal for these manually while I raise it for other trackers that are less healthy. Having µTorrent automate this would be useful.
µTorrent could/should allow to this effect rule-adjustment by tracker url, label or possibly torrent health (seeder/leecher ratio).

Add support for multiple watch folders, with the ability to assign a label automatically to all torrents imported from that folder.
This feature would be particularly useful when the user chooses to use their own automated download systems in lieu of uTorrent's RSS feeds

Please, add Atom feeds support to the uTorrent.

I suggest you to make search in downloadable "Files" screen. If i download torrent with 6000 books it's hard to find the one i need, if i don't download all 6000 books.

The coming Windows 8 has a Metro UI which uTorrent should create it's app in.

Vote down ideas in the idea bank. Stupid/unreasonable ideas need to be retracted, and voting down would allow this. If admins thinks this would be abused, voters should specify a reason why is should be voted down.

Allow users to specify which day of the month the available bandwidth for transfers should be reset. The current "last x days" is good however not ideal as I have exceeded my limit by a day :/

Make such a button, in right mouse button menu.

Can you make the auto shutdown options part of the scheduler. Currently if I want to use the scheduler and shutdown afterwards I have to wait for the downloads to start before choosing the shutdown option. If I want to use off peak time that means I gotta stay up fairly late.

I would like to be able to enable the scheduler at 9pm to start downloads at midnight and auto shutdown when downloads are complete.

simple stuff. All I want is a small progress bar when utorrent downloads an update.
An update is never successful when my family is on the pc! They just think its stuck and close it!

Have labels that are "smart" labels, similar to smart folders in iTunes, where they include subsets of torrents that fall within filter specifications. i.e, torrents with size above 5 gigs, torrents that have less than 5 seeders, etc.

Add comments and notes to the torrents.

I love the country flags to see where I'm connected to. But I would love to see the full country names too because I don't yet know all the flags or TLDs. Please show the full country name when I mouse over the flag. A separate column for the IP country name would be great too.

Columns should retain sorting preference across window/tab. For example, uT should remember that I prefer my "Completed" tab to be sorted by the "Completed On" column and that I prefer my "Downloading" column to be sorted by "ETA."
