Some task would stay for weeks without downloading or uploading. Would not be better for the user to be worn that those tasks haven't uploaded or downloaded any data and prompt him or her for remove.
I know that a plugin that monitors the upload idle does something similar and it doesn't worn the user when removes the files, but if would be based on the share ratio and the calendar would be more reliable.Just an example: If it doesn't go up by at least 10 percent in a month remove the task.

... if any URL torrent have.

Just little easement there, but asked several times.

Some movie torrents are in other languages and do not come with the subtitles. It would be awesome if vuze had an app or service that automatically searches for srt files for those downloads or ask before download "This file does not include subtitles. Would you like to find them?"

allow for manipulation of font types, sizes, and colors of text.

When you add a torrent you can check the availablity of torrent before proceeding. It would be great to get that same option once you have started/completed the torrent to see if you need to re-seed the torrent. It might even be a good idea to add an option to auto-check archived or completed torrent to see if they have no seeds anymore.

Option at first run or wizard later to switch on encryption and add IP filter lists automatically, so downloading can be as secure as possible right from the off

Azureus has a DHT implementation that is incompatible with the mainline DHT implementation that pretty much every other torrent client uses.
And while a plugin exists that solves this problem, it is not installed by default, and thus many users do not have it. This hurts both their their user experience(they cannot find approx. 80% of the peers via DHT) and the whole swarm's too(they cannot be found by ~80% of the peers via DHT).

Bundling the mlDHT plugin with new Azureus releases would solve these problems, and it should be very easy to do.

This would allow me to see the upload/download speed all the time.
The application "Transmission.app" has done this for years. I miss this small yet helpful feature.

Vuze Remote lets you control Vuze remotely from a Browser but requires that you either have a UPnP enabled router or that you manually map the required TCP port. Please make it work for users that don't satisfy these criteria.

when I watch a movie on a TV from Vuze, there is no way to control its playback right now (play/pause/ffwd/frwd/skip to next chapter).

Thanks for adding this feature, should be easy to add it within the app on the PC, not sure if you could link it to the TV remote which would be fantastic.

I use Mac (if this matters).

A pop up would appear that help newbies navigate and learn easier

Would also be great if it would be able to stop a move operation after the current one has completed (when more than one torrent has been selected to be moved).

would be nice for vuze to identify peers in the swarm that are only leeching and not sharing..and alert the user to this activity and give the user the ability to ban that user either for a limited time or forever

how it would do this is...it would keep track of how much data a partiticular peer has sent..and if its below a certain amount over a certain period of time..they that client is most likely only leeching

this is very wide spread with XUNLEI clients

Instead of only allowing one level of folders for streaming to devices (i.e. Xbox 360), you should be able to nest folders within other folders to better categorize your media. So instead of "Movies>[Huge list of movies]", you would have "Movies>Comedy>Slapstick>[Much shorter list of movies]".

Most video majority of people download using torrents are rared and split into multiple files. It would be a great addition to just be able to drag the torrent to the device for playback and be able top watch it. Without the need to extract it. Llink is another media streaming app which has support for this. Think this would be a great addition to Vuze. http://www.lundman.net/wiki/index.php/Llink
