I installed 13.1 last night and started playing with KDE4.4.3. I'm talking about Konqueror as a file manager only here. My default view is to have the folder tree in the left pane, with a detailed view pane on the right. In KDE3, I use the "Tree List View".

In KDE3, I had my mouse set to "double-click to open files and folders". However, in KDE3's konqueror, you could still navigate the folder tree with a single click. One click on a folder in the left pane would show the folder's contents in the right pane, or a double click in the left pane would expand the tree to show subdirectories. I could still single-click on files in the right pane to highlight them without opening them.

In KDE4's konqueror, it requires a double-click to do anything with the folders, either to display in the right pane or expand the tree. It's a lot more effort just to get around in the folder tree. I found the Mouse setting in the System Settings that changes overall single-click/double-click behavior. If it's on single-click, it's easier to navigate the folder tree but then I end up opening files I don't want to just by trying to highlight them with a click.

I dug through Konqueror's settings in both KDE3 and KDE4 but couldn't find what gave me behavior I liked in KDE3 or how to duplicate it in KDE4. In KDE3, the system setting is on double-click, but there doesn't seem to be a konqueror-specific mouse setting to customize it. Anyone else notice this? Is this hard-coded into konqueror, and it changed from 3 to 4?

I seem to have solved the problem. Although I may have perceived it to be more of a problem than it really was. It seemed like I was having to do a lot more double-clicking than usual to navigate than in KDE3. Now that I've tried it again, KDE4's konqueror seems to act just like KDE3 did with the mouse set to double-click.

One thing that helped - I went into the Menu Editor, and copied the Konqueror shortcut from Internet to System. In the new entry, I changed the command from:

to:

I then saved the menu, went to the shortcut in the System folder, right-clicked on konqueror and added it to Panel. Now I've got a something similar to the old Home icon on the taskbar in KDE3.
