I completely agree with the changes of Carlos and the additions of Pierre
regarding this behavior. I am trying to convince people to switch from
environment like matlab and I think that this change is both minor,
harmless and helps beginners.
However, the problem I mentioned earlier is a bug to me. It is a problem
of focus:
If you have both the console widget and the ipython console widget opened,
with the cursor/focus in the python widget and you click on ipython console
tab, the pure python console keeps the focus and further hits on the run
button will be executed in the console. When the one does the reverse (put
the cursor in the ipython console and click on a normal python console
tab), the focus moves as expected to the python console.
I hope I was clear. I think that this is probably a one line fix. I can try
to look at it.
Cheers,
Sylvain
