Build 136 Dev 3 : Custom Project : We can not reduce Task View if we have many tasks

In Custom Project, in a project, if you look at the tasks on the left side of SQX , 


If you click on the right arrow , to see all the tasks, (Please Attached capture1),


1/   You will see the first part of your tasks on your screen, but you can not access to the following tasks,  (Please Attached capture2),


2/   You do not have access to the left arrow to reduce this view either 


The only thing we can do , is to enlarge SQX windows over 2 or 3 screens , to see the following tasks and reduce the view by clicking on the left arrow (please capture 3)


What happen if we do not have 2 or 3 screens to enlarge SQX to see all the tasks and reduce the view ?


What happen when the number of tasks is more , and we do not have enough screen to enlarge SQX on them ?


Could we have a scroll bar at the bottom to navigate the task ?


Is it possible to make sure that we have always access the the left Arrow to reduce the view  even if we have many tasks


Actually if we have many tasks, we do not have access to the left arrow to reduce the view
