A system is composed of files and applications using them. Traditionally, we do not separate them but access them all through one window after another. Most mobile systems solve this by application-driven hence just depreciating the file manager, while most desktop systems still use "file manager", "find", "desktop shortcuts" or other ways to search down a file.
A simplified and unified way would do much help.

im using HUD for a while and i think its should be intuitive to open an installed program from HUD, so you dont need to have shortcut for everything.

It is not possible to move or delete Workspace Switcher, Trash icons in Ubuntu 12.04.

I would like to have Workspace Switcher icon as the first icon (or second if we count with Dash icon). I have many icons in Unity panel and I need to scroll down and find Workspace Switcher icon to be able to click it with mouse.

I would also like to remove Trash icon completely to make space for app icon.

It is really annoying to move/resize newly run app window to the position that is comfortable for me again and again.

Ubuntu doesn't currently support remembering the position and the size of all app windows.

Several cases:

I run "Terminal" and move it to my comfort position to the left bottom of the screen. After some time I close it. When I run it again it opens somewhere else and I need to move it again to the left bottom. And that happens again and again.

Surprisingly, it works for LibreOffice Calc. This app remembers its position and size. Probably because it was implemented by the app and it decides where to display. But what if I want to display all app in the center? For LibreOffice Calc it wouldn't work.

It would be good to set this behavior in one place for all apps, eventually add some exceptions if are needed.

There should be the same login time displayed (24h/12h, time zone, language) as it is displayed after a user signs in.

Currently users can see e.g. "4:50 pm" in the login screen top bar and after they are logged in they see "16:50".

HUD is able to search all the menus in the panel; including those in app-indicators. For instance, if I want to play a certain playlist, it is accesible from HUD. I would like to see better media control from using HUD. If I would like to pause, or skip a song, I want to do it fast. Currently right now, because these actions are buttons within the sound menu, they cannot be used with HUD.

Hi, for a while I did try GNOME-Shell, but did back to Unity, in all this process I miss only one.

When use the effect pointing the arrow up left conner, all windows in the desktop show, then I did activate same effect in my Unity, but something missing. The Close button in the arranged windows are not.
