The very purpose of having dual pane is to transfer the folders/files from one pane to the opposite pane.
And the tabs enable us to load different locations in the panes. 
Typically, the left pane is the source pane and the right pane is the destination pane. 

This is the logic for loading specific locations in each tab.

But the Dolphin does not follow this logic: 
Each tab has two labels (one for the left pane, the other for the right pane.)

When we switch between the  panes, the URI loaded in the active tab changes.
But the labels in the other tabs do NOT change.

This is extremely confusing.
The solution lies in following one of the following alternate designs:
Option-1: Each pane should have a separate set of tabs. When we change the width of the pane, the tabs of that pane must re-size to fit within the available width.

Option-2: Keep the common tabs, but each tab should show the locations for both panes.
For example, a tab could show "Home| Downloads", which means that if this tab is selected, it will load the "Home" folder in the left pane and "Downloads" folder in the right pane. 
(The pipe symbol "|" is used as separator.)

Reproducible: Always

Steps to Reproduce:
1. Launch a few tabs.
2. Select the tab#1. Switch to left pane, and load a folder. Then switch to the right pane, and load another folder.
2. Select Tab#2. repeat the selection of two different folders in the left and right panes.
    (take care to select a different set compared to tab#1)
3. Repeat for tab#3.
4. Now select any tab, and then select the left/right pane. Watch the text in the current tab.


Actual Results:  
Each tab remembers the folders that were loaded in the left and right panes.
But the user does not remember these bewildering combinations.


Expected Results:  
Each tab should display a dual folder locations (for the left and right panes).
OR make a separate set of tabs for each pane.
