Can you separate three red lines on navigation bar? All three red marker lines are lnked to left file scroll bar. That's not what it should be.
Left and half of the middle line should be linked to left scroll bar.
Right and second half of middle red line should be linked to right scroll bar.
Left click on left half of navigation bar should 'jump' to left file.
Left click on right half should jump right file. (currently only left file is linked)
There are also possibliities of linked scrolling, sync scrolling,
