h5. Description
In Package Manager window details pane, action buttons are located at the top-right of the window. This becomes problematic when the window is docked. Resizing horizontally the window does not do a good job at bringing action buttons closer and often, an horizontal scrollbar is created, which confuses users: vertical scroll vs horizontal scroll.

The UI of the details pane should be more responsive and adapt to different resizing.
