           Summary: Digikam automatically expands folders while dragging
                    over them
           Product: digikam
           Version: 2.3.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: thomasdn at gmail.com


Version:           2.3.0 (using KDE 4.7.2) 
OS:                Linux

When a user drags a folder over another folder in Digikam, the folder is
automatically expanded. This confuses users and makes it very easy to
accidentially drop the folder in the wrong album.

A screencast illustrating the problem is available here:

I see three problems here:
1: The automatic folder expansion can be useful in some use cases, however, it
is my experience that it confuses users more than it helps.
2: Appearently, there is no way to disable this behaviour from the Settings
window.
3: .. and this is probably the detail that makes this behavior most
annoying/dangerous: the folder expansion happens too quickly. I am guessing it
happens after hovering between 1 and 2 seconds. This is just too fast. Many
users require much longer time in order to position the mouse correctly. I
would say between 3-5 seconds would easily be needed.

Recommended solution:
1: Provide an option to enable/disable this feature.
2: Set the default bahavior to have this option disabled. (I think other KDE
applications such as Dolphin, etc. also have this feature disabled by default)
3: Make the delay before folder expansion configurable: let the user set the
delay from a range between 500ms to 10s. Set default value to 4s.

Reproducible: Always

Steps to Reproduce:
Drag a folder over another folder containing subfolders.


Actual Results:  
Folder expands very quickly

Expected Results:  
Should not expand -- or there should be a bigger delay.
