I launched an issue to the provider of the package for this enhancement yesterday, but there is still no feedback.
In the meantime I checked other packages and found the package "terminal tab". This is providing you a terminal within the atom surface, where you can launch clickable like in a desktop shell. So you need not to change between windows/applications. This may help in the meantime.
Any other supporter is welcome too (and required for my impression). It would be great if we can find a specialist for atom extension packages who is willing to prepare some improved tools for development.
@advocatux : Yes I have seen it, and there are some interesting options still to evaluate. I already tested the log command, which is quite helpful and a first step to see roughly what is going on. It still cannot replace a good debugger.
