The Global viewport: Open the RDX Settings to set the values of global viewport. The RDXParent frame will be resized, making all the UI of RDX resizing.
The Local viewport (or desktop viewport): Open the desktop tool, option tab. Only the Worldframe will be resized.
Awesome! I just patched via Curse Client, and will test out an alt later. I still wish Syla's Main Frame did not include the minimap cluster by default part of said frame; rather have the MM be its own thing. Otherwise, looking forward to poking at the latest build!!
