Program to control multiple instances of other program

Hey guys I have developed working application which works in backgroun and only logs actions so I can check if its working as expected

but I am running multiple instances(each with own executables and files) and its overwhelming to control all of them separately

whats a good approach/pattern to control them with another application? my idea is there would be a GUI with tabs for each application and would be able to run process and terminate process. preferably with option to copy and create another instances as needed

Your idea is the way to go.
I used the same approach for one of my projects.
Take a look at the screenshots :)

Well just a stupid question, why do you copy the files?

I mean you could simply use the same files, or, if there are config files which get edited, use a different working directory and link the files that don't get changed. Otherwise you are wasting space, and a lot of time, as copying is very slow, and also the files that dont change can be cached by the OS
