the linux file system structure isn't that great. a bunch of stuff is grouped by the file's purpoes instead of grouped with the application. some examples: there is a /var/log directory where all applications go to when they want to log information. apache creates a /var/www which is the folder which gets hosted. the root user gets its own folder at the base (/root) instead of /home/root like everyone else. temporary files (normaly found in /tmp) should reside in /tmp.

As the option to minimise a window or an app using it's icon on Unity Launcher is removed, it is a bit difficult to use the minimise button on window title bar every time we want to minimise the window or an app.

By using this formula we can reduce the decision algorithm or logical test to single mathematical equation or algebraic manipulation. Therefore we can make elegant programming. It saves time memory and energy. The complex program can be executable in ordinary processor. We can develop software that works on ordinary processor. Therefore it can be useful for mobile tablet and all computers.

Currenlty System Monitor is a seperate app, and would be better as unfied experience if it weren't.

Huge number of items in Context Menu is making it hard to find the one you are looking for. Cutting down number of items reduces functionality - keeping them increases time to select the item. Additionally, bad organization of items increases mouse movement.

Web browsers – like the default for Ubuntu: Firefox – are currently using an extra windows to manage downloads.

When you have to do an update and you want to shutdown the PC (or reboot) but you can't stay in front of him you can't choose before the behavior. Today you have to stay in front of him.

Whilst it is one of the strengths of ubuntu that you can install it without following a lengthy procedure of multiple prompts, I feel that more options should be provided after installation has begun (at the stage where the twitter feed shows up and the features slideshow has ended, I. E. Once most of the data copying from cd is done ), which would allow the user to set up other vital services.

Once installation is complete the user still has to set up his email (which may be more than 2-3 adresses) and their social networks.

The basic problem with Run Command (Alt+F2) is that it can not take "sudo" commands; sudo requires a followup query to input a password. About 95% of the commands I use in terminal require a password, such as adding ppa's or installing software from a script. Thus, the alt shortcut is 95% of the time useless.

In my search for a solution, no lens appears to exist. I found two mockups of what this would look like. The one at this link is the nicer of the two:
http://askubuntu.com/questions/259234/where-do-i-find-a-terminal-lens-for-unity
In an answer to his query, "Teester" said this: "There is currently nothing that does exactly what it pictured above since, at the moment, a lens cannot define a content area like the one pictured in order to display (and update) the output of a command. "


The other mockup was given as a solution to another brainstorm idea (http://brainstorm.ubuntu.com/idea/28565/). That idea was resolved, however did not address the issue I am bringing forth. Anyways, here is his mockup:

edit:
Disregard the "Alt or " in the title. I learned something new today, mainly, that the Alt button is program specific.

these are ideas or suggestions to improve new notification server or message indicator usability.
