Hi. This update fixes some annoying bugs ( color to albedo I mean you ), adds more zoom options, introduces functionality to some nodes, which should have been in version 0.2 but we trivially did not have time. 

Changes: 

• In the Mix node, the number of blending modes has been greatly increased.  Added ability to change transparency for foreground and background
• In the Tile node, a general scale parameter has been added 
• Added an alternative mode of scaling with the Alt + Rmb hotkey
• All selection and cutting operations can now take place over the frame
• Frame can be dragged by grabbing its title bar 
• Frames can now be colored in any color
• After selecting the nodes you want, you can put them in the frame with the hotkey Ctrl + F or by adding a frame through the right-click menu
• Now if you forget to save your project and try to exit the program will ask you to save your work
• Fixed an error in transferring color from the Color node to the Albedo node
• Fixed displaying reflections in the Material view

If you see that something works wrong, please don't be afraid to leave comments, it will help us a lot.
