#10. Individual Passwords
Currently security is limited to one password per service, which must be given to all the people who will have access to it. To remove one single person's access to any given service, the new password must be re-sent to everyone else.
This is fine if removing access isn't going to be an issue, but otherwise it would be nice to have the option to associate different passwords with different email addresses.
#9. Torrent Tracker
File Sharing is great for those with a lot of upload bandwidth to spare, but for those of us on slower connections, sharing large files with many people can become a problem. Bittorrent is perfect for this situation, which is why I'd like the ability to run a torrent tracker.
Like running a web server in general, running a forum from a home computer is possible, but extremely difficult for anyone without much technical knowledge. It would be cool to be able to do it without having to learn anything about PHP.
#7. Voice Chat
Unite already has text chat ability in the form of the Lounge, which makes voice chat an obvious next step. Chat with anyone with a browser and a microphone!
#6. Bookmark Sharing
This is a fairly simple one: a service that displays whatever Opera bookmarks are currently saved on the computer, arranged the same way they are in the bookmark list.
This could be used to share bookmarks with friends or just to have them available from any computer no matter the browser. It would be even better if bookmarks could be selected for sharing by folder the way files are in File Sharing.
Unite can already be used to make a basic website, so why not a blog? It would make things much easier for anyone who needs to update their website regularly, and would obviously be great for people who just plain want to run blogs from their own computers.
#4. More Informative Progress Bar in File Uploader
This was originally further down on the list, as it's such a small thing that it didn't strike me as that important at first. The more I use File Uploader, however, the more the vague upload progress bar bugs me.
Is the file really uploading? How fast is it going? How far along is it? How many files out of the group have actually finished? Upload more than one file and it will start to drive you nuts. It could be fixed with just a little more information on the screen while uploading, though.
#3. Drawing Board
The Fridge allows people to leave little notes on your computer. The drawing board would allow them leave pictures. It wouldn't need to be Photoshop-level; just a little paint program to draw a picture, for those messages that simply need to have more than text.
#2. Document Viewer
Ebooks and other documents can already be shared via File Sharing, but it would be even more convenient to be able to view them in the browser itself, without the hassle of opening an outside program. The document viewer could also allow comments to be made on each document, either to give feedback or just allow for a shared reading experience.
There are plenty of things I'd love see in Opera Unite, but this is easily #1. Wikis are great because they allow large numbers of people to share information with each other without difficulty. Unfortunately, while they're easy to use, they're far less easy to set up. There are plenty of sites out there that will allow people to set wikis up for free, but generally the cost ends up being paid in ads on the page or severe space limitations. Being able to simply install a wiki service in Opera Unite and immediately have an ad-free, functional wiki for people to post to would be awesome.
Because really, isn't sharing the things that are important to you what Opera Unite is all about?
