I have done some improvements on the GUI mainly the tree view menu and avatar controls. The list of changes are stated below:-

Tree View Menu

• The size of the tree is now fixed at 20% of the total world width and the height is fixed to below the menu bar right down to the bottom of the world morph.
• The size of the tree changes and keeps its aspect when the world morph is resized.
• A lot of empty tree node errors fixed. If you find any, please let me know.
• Right-click on tree nodes to show pop-up menu added.
• Fixed error of collapsing on empty collection when a child node is still selected.

Avatar controls

• The avatar now moves smoothly using the keyboard controls (w,a,s,d…etc) without needing to wait for the OS key repeat to happen.
• Going forward with ‘w’ key will no longer have avatar blocking your view in first person mode.
• More than 1 key can be pressed now for diagonal movement e.g. w+d .
• Holding shift key when clicking and dragging on a cube will allow the user to move around the cube in a circular motion for full body view.

Others

• Input field on windows now accept changes and stores the value when text is modified. Previously, the user had to hit enter or tab before the value is accepted.
• Some small and little improvements not worth mentioning here (cant remember all too).
