I made a number of modifications to the standard Houdini GUI that focuses on increasing the productivity by maximizing the screen estate to its limits. Here are some of the changes:
1. Network editor is an overlay over the viewport or the render view, depending on what's visible. It allows working with the network editor while simultaneously seeing the result of the node network, with configurable opacity settings (0.25, 0.5, 0.75, 1). The network editor can be toggled away from and into the viewport using a single key.
2. The whole application is in full screen mode, that eliminates the taskbar and the titlebar of the application.
3. The status bar is at the top inline with the main menu bar.
4. The shelf is completely outside the visible screen space. It can be accessed using the viewport TAB menu instead.
Special thanks to Jason Iversen for his overlay network editor sketch.
