Feature Request: save a snapshot for use after relaunching program

[kerrhyphen]

Hi folks,

Not sure if this creeps out of scope for the project, but I would love the ability to save a multi universe snapshot for later use, rather than having to re-set each universe output every time the application is launched. The old "address 512 is set to the universe number" trick is a huge timesaver for us when confirming gateways and dmx runs have been set up or moved properly, but it is a little cumbersome (and sometime error prone) to have to click through 15-20 universes and manually configure each one. Being able to save a snapshot that either persisted between launches, or could even be loaded from a file, would be a great help.

Thanks!

#335 fixes this for Receive windows, should extend that for Transmit
