Editors
When a project is built or run, each .pxr file will open in an editor. You can also open
files manually. The type of editor a .pxr files opens in will depend on the root type
(video, audio, gui, etc.).
At the top-right of the editor region are four icons. Three of these allow you to
switch between open editors. The maximize icon 
allows
you to enlarge the editor area, minimizing all the other windows to the sides and
providing more workspace.
All editors have their own toolbar, which contains at least two buttons. The play button
toggles whether the root is active. The root properties
button 
opens a window allowing you to set properties of the
root component (such as video resolution and frame-rate). Not all root properties
can be set while the root is active.
You can save a .pxr file at any time when the editor is active. You will also be
prompted to save whenever a project is cleaned. Due to its distributed architecture,
PraxisLIVE does not attempt to track all changes so will always prompt you to save.
