There is no scroll bar on the "black-left-panel/column" listing the "storage locations"

[AlexisEspinosaGayosso]

Since upgrading to the newest version (0.15.0), The app in my mac lost the scroll bar on the "black-left-panel/column" that contains the list of the "storage locations".
The scrolling on the list is very important, so, please, fix this issue and put back the scroll bar for the mac version. Scroll bars for the other three panels (notes, raw text, formatted text) just work fine!, but no the storages one.
Many thanks.
