The propose here is to remove the Tree View used in the widgets explorer in vertical orientation. In its place, use the same button of the horizontal orientation, what simplifies the code (removes a class and some checks) and improves the use of space as the widgets list can grow vertically.
Better if combined with http://reviewboard.kde.org/r/4676/ as we also gain the space currently occupied by the arrow buttons and the close button in the bottom left corner.
The screenshots attached show the current widget explorer with the categories tree view and the proposed one, using the categories button.
