ubuntu should have a webcam control panel app where would be possible to set configurations like brightness, colour, exposure, etc while we are using the webcam in any application.maybe some effects too.

"guvcview -o" provides a control panel for web cameras and has ability to save and load settings. A suitable location for entry could also be System - Preferences.

Some work for it would still be required:
- ability to select device from the UI (if multiple cameras has been connected)
- ability to silently and automatically load predefined configuration for a camera during login/system startup.
- only works with UVC cameras, support for cameras with random data interfaces would be much harder to implement

I don't know if there would be any design trade-offs between speed and lifespan in such a profile but SSD's short write lifespan issues are a bit of a myth so if a call needs to be made between them we should go for speed!

See this site for why it's only a problem on the smallest of devices...

Why not make the SSD option in the installer for all file systems.
It is easy to create it, simply activate SSD mode in ext4 and btrfs and write "noatime" into /etc/fstab.

Here's how it could look like:

(This may be just an addition/clarification to solution #1)

If a SSD is detected, the installer should inform the user how suitable a certain filesystem system is. In particular, if it supports the TRIM command.
Depending on the user's experience, there could be just an indicator (green, thumbs up...) or a complete explanation of the benefits of a filesystem with TRIM.

Power off after umount is not a good way to do it, because a flash drive might also have several partitions. Umount one partition whould actually turn off the rest. Adding a new option to Power Off usb disks which whould first umount all paritions whould be a good idea.

Left button click is already simulate by tapping, so I want to propose something similar for RIGHT button as well.

two finger tapping - right button click

I think that this could be very simple and effective way. (We can possibly take this to extend and use 3 finger tap for middle button, but I'm not sure about it...)

The two-finger scrolling feature is good, but when turned on, horizontal and vertical scrolling with the edge of the touchpad stops working. It should be possible to use either option with the same settings.

Start moving towards the 10/GUI idea, perhaps create a new Ubuntu version that is designed with touchpads in mind (see concept video). The new distribution should still have basic support mice, but should work on simplifying the desktop using multi-touch technology at the same time.

Nathan Harrington, an IBM developer, has written some Perl programs to detect multi-finger swipe and pinch gestures on Synaptics Touchpads (the only type with a good enough driver to do something like this) at

http://www.ibm.com/developerworks/library/os-touchpad/index.html

These could be run as a daemon to perform actions when gestures are detected. Also, instead of the SendKeys Perl command, one could use xdotool ( http://www.semicomplete.com/projects/xdotool/xdotool ) and put system("xdotool whatever") in the perl script (this would give you more flexibility than SendKeys, for example mouse clicks/movement).

There needs to be a generic tool - that works with major vendors - supplied with Ubuntu, and installed if computer=laptop, which can effectively manage battery thresholds. Additional information could include number of battery cycles, wattage, among others.

In my opinion it would be better to extend the current tool (maybe by optional addon which can be installed just for laptop users), so all power management options are at one place.

Also it would be nice to improve the battery capacity detection - for example on HP nx9420 my battery "designed capacity" is not detected correctly and instead it's set to the "last full capacity".

These days laptops mostly run on lithium-ion batteries. They don't suffer from memory effect, so they can be recharged anytime without ill effects. However, they can lose their capacity pretty quick, sometimes halving their capacity after just one year. I've destroyed three laptop batteries myself like that. Now I've learned a bit more about them because I got a job working with them.

Although you can maximize the runtime by optimizing how much power/current the laptop uses, it won't help make your battery "live" longer. How you use your battery affects it more. You can actually kill your battery pretty quick if you constantly keep it plugged in the wall and recharge only couple percents every now and then.

Not many laptops let software control how the battery recharges, but if that is not available, the OS could at least give user suggestions to when to un-plug or plug-in the power. Not just give a note when the battery has just reached 100% or is nearing critical. If software control can be done, it would actually beneficial for lithium-ion batteries to stay around 60-80% instead of 100%. This of course needs to be user controlled for situations when 100% is really needed.

Currently the visuals show how full my battery is. I need this information when I want to know, if my battery is full or not. How about concentrating on visualizing time left, and using some smaller clue to show whether or not the battery is full. I'm thinking about showing a pie chart that works as an analog clock.
