Not automatically propagating system environment variables

Hey Guys,

Im working for a Company where we working sometimes with Enviroment Variables. I always compile and start the Programm with Flow.Launcher. Thats easy and fast but when i working with Enviroment Variables i have to restart Flow.Launcher or start it manually.

Normaly all Programs when they start other Programs they give them their version of Enviroment Variables. So when the programm is started and the Variables changed then the Program has the Old version of the Variables and start Programs with that Old Version.

It would be nice that the Programs always start with the newest version of the Program variables. (If it is Possible)
I tried to create a Plugin with that feature but i dont get far. I want to do this part of my life faster maybe you can help me with that.

Cheers
Tobias
