I really like the bread crumb mode on the location bar, but in a folder with many sub-folders, it is basically useless.  I have one directory in particular that has 250+ sub-folders that shows this deficiency in glaring detail.  When I click on the arrow to show the list of sub-folders, it opens up a list that fills the screen and then has a second column that contains a single option of "More."  I can then click (or hover) on the "More" option which will bring up another similar two columns with more sub-folders.  I have to do this 9 times and cover the entire screen before reaching the end of the list.  It would be much more usable if the list was in one column that scrolled instead.  Please make the list scroll-able instead of the "More" option.

Reproducible: Always

Steps to Reproduce:
1. Open Dolphin
2. Navigate to a directory inside of a directory with many sub-directories
3. Click on the arrow in the location bar following the name of the directory with many sub-directories 
Actual Results:  
See the "More" option column instead of being able to scroll the list of sub-directories.

Expected Results:  
Should be able to scroll through the list of sub-directories in the pop-up menu (as if you were in the main dolphin window).
