ability to launch multiple instance of ubiquity

I don't know what umbbs needs it for, but in my case: I wrote a command in the old syntax which I use very frequently (need it all the time). Now I want to "translate" it into Parser 2 syntax. So I have the choice: do I switch between the two parser versions all the time? As long as I work on the translation I can't use my Know Command... Having 2 instances would be an advantage here. Keep in mind that people do not have time to work on experiments with parser 2 continuously - you can only do some work in between when you have a break from other todos. With a second instance you could keep a "building site" with different configurations.
