Button to launch to a window in a different Project

Could I use system.nav.swapTo in some way to retarget a different project window??

You could use the system.util.retarget function to retarget to a different project and at the same time open the windows you want opened.

The system.util.retarget function includes an optional argument that contains a list of windows you want to be opened on the project you are retargeting to.

Here is the manual entry for system.util.retarget:
