ATM it is very uneasy to edit system files as root with a GUI.
E.g. if you want to edit files in /etc, /boot/ etc... you have to go to the console, get root and edit the files either with nanno or with "sudo gedit" (GNOME) or "sudo kate" (KDE).

It would be a good idea to integrate a "Administrator mode" button or something like this with policykit backend into nautilus/dolphin.

I think for nautilus is something lika that underways, but for dolphin not.
To access root-only directories a question while entering the dir would be ok, but for editing files e.g this is not enough.

Other solution would be - every time I don't have the rights to do something (save /etc/samba/smb.conf e.g.) the systema asks me for the password.

Note: Perhaps this has been added in nautilus, I am using KDE at present, and its version of nautilus may be old (2.30.1).

Suffice it to say, this is an elusive (at best) feature that i really miss from Windows. It had an option when you right-clicked an image file, to 'Set as Background' or similar. In Dolphin and Nautilus, there are no options for 'setting as desktop background'. I know that there is a plugin for nautilus to allow this, but the end user wouldn't know of it. And in KDE, you just about have to use the 'Desktop Activity Settings' module to change your wallpaper. Even Gwenview lacks this option... while M$ Picture and Fax Viewer has it. The current 'desktop settings' apps in gnome and kde have only the option to import images one by one. It would be useful to allow importing an entire folder, that the program would find all the image files from, and show them in the list.

Sorry to rant, I love all the *buntus, it's just a small issue anyhow.

this is a request to support ctrl+z when an item is moved from "somewhere" to the Bin in Dolphin.

In Dolphin one of the default options for a folder or file is to encrypt it. However kgpg is not installed by default so when you try it tells you that it cant encrypt it.

Personally, I dont think there's any need for an encryption option by default, but whether or not there's a need for it, if youre going to offer it by default surely it should be a real availability.

Dolphin has a lot of really useful service menus and preview plugin... why not install them by default?
For example the packages:
kde-menu-service-fuseiso: allows to mount an iso image
kde-menu-service-audiokonverter: convert an audio file
kde-menu-service-rootactions: run actions as superuser
kde-thumbnailer-openoffice: shows preview of openoffice documents
kde-thumbnailer-audiothumbs: shows the cover of a music album
kffmpegthumbnailer: shows preview of videos

Actually these packages are present in the ppa:samrog131/ppa repository. There are also others service menus that are useful, like:

when you copy many files, soon you will have a plenty of windows with transfer status

they could be joined in one, with tabs

something like this
(sorry for my gimp skills :) )

this is really great thing in konqueror - for ex when you copy a big file from another computer in the network, and for any reason, transfer is not completed, next time you try to copy the same file into the same directory, it asks you if you'd like to continue the transfer, so you dont have to wait another time to finishing the transfer

in dolphin i miss this function :( could it be implemented?

Basically this is the "same" idea as force Nautilus to open in new tab instead in new window, just for Kubuntu.
-------------
Dolphin has split view option which is even better than tabs as you can move your files much easier from folder to folder.
So when I have my Dolphin open and I want to open another Dolphin the first Dolphin should just split view to a folder that I opened with the second one.
If there is already a split view opened in Dolphin it should add a new tab instead, then split view, then tab again...

I hope you get the picture.
And if I close split view in both tabs they should be merged in one split view.

I often work with files and directories with Dolphin and have the need to rename a lot of files in the same manner.
pyRename is e.g. a nice tool for that, easy to use and with powerful features.
However, it sucks to just go to the k-menu, open pyRename, navigate it to the directory that I have already open in Dolphin, and then, finally be able to start renaming.

EDIT:The problematic issue seems to be exclusively in Dolphin. I do not, for example, find it a problem with gthumb
RELATED: http://brainstorm.ubuntu.com/idea/25678/

When loading a folder that has a large number of images, the presentation of the thumbnails always takes a long time, and until they are all loaded the sequence of the images constantly changes; making selection almost impossible.

I suspect the problem is that thumbnails are always retrieved in a "sort by name" sequence. But if the folder is sorted "by date, descending" the mismatch between the two creates a rather long wait state for the user before they can click an image.
This is particularly annoying in situations where the user is opening a web browser "file upload" dialog to upload a single image file.
