Here's the use case: I have a laptop that I use at the office and at home. At the office I have a Canon IP5000 printer, at home I have a Canon IP3000 printer.

When I want to print a document, the IP3000 printer is always selected, even if it is not connected (and indicated as such), adding an extra step to select the IP5000 printer if I'm at the office.

One of the side effect of that is that I often print a document without noticing the the IP300 printer is selected (but not connected, as I'm at the office). I then have to cancel the job in the job queue, reprint and select the IP5000 printer.

Another side effect is that if I forget to remove it to the queue, the documents that I wanted to print at the office get printed when I dock the laptop at home (the IP3000 being connected, its print queue gets processed).

This would not be necessary if the print dialog was selecting the first online printer instead.

ubuntu has really nice effects like minimizing window animation and so on but I think people should get the ability to manage this effects so
I think Visual Effect settings menu should be integrated directly to ubuntu yes some one might say that there is compiz manager but it requires a separate download and plus it is a mess to use I have this problem if I change something I never can make it as it was before

I believe this would prevent many first-time users from being discouraged when they first use the terminal.

The "Spread" view in 12.10 is nice. But what I really miss is an easy way to close unneeded windows from there. There is the close button for each window. But this button is tiny and you have to aim for it. This is very annoying. On top of that, I didn't even see this function/button until I read about it in a blogpost. I always thought that this is just the window title bar and always overlooked the close button or the very possibility that this is actually a way of closing windows from spread view.

Everytime I am in spread view, I wish I could close unneeded windows by simply clicking in that window. When clicking on a launcher icon with middle-mousebutton, a new windows of that application is being opened. So it would make sense that with a middle-click on such window in spread view, a window will close.

A lot of users are dissatisfied with the integration of the Amazon shopping lens in Ubuntu due to its many disadvantages such as the privacy issues or the use of the internet connection.
However Canonical need to earn money somehow to pay the developers.
Most likely they will remove the shopping lens or make it optional, if we (the community) suggest other effective sources of income.

1) A customizable installation (with checkboxes o something similar) you will be able to choose what packages do you want. You will can select or unselect the programs that ubuntu install as a default, if you dont need an email client you will can unselect it...

2) Integrate in 1 DVD unbuntu, kubuntu, xubuntu... you need only select what desktop do you want and what packages (see nº1)

"Ubuntu should be available as a live/install DVD that comes with Gnome, KDE, Xfce, and perhaps other desktop environments. Ideally, it would have equal priority to the CDs that only come with one, which would include being released at the same times. When booting from the disk, users should have an option of which environment to use. When installing, users should be able to chose which environments to install, and have options for installing additional packages designed for those environments (like the gnome and kde packages).

This would allow multiple people who prefer different environments to use the same installation disk. It would be more convenient for people who want to have e.g. both KDE and Gnome. It would make it easier for people new to Linux to learn which environment they prefer. It would make it easier for lesser used environments to gain new users. It would put all supported desktop environments on a more equal ground, rather than sanctioning one as the only "real" and "official" desktop environment for Ubuntu."
