How about adding "(Qt3)" to the label of the default one and change "no
Qt" to "no Qt3"? That would IMHO be more clear as to what the default
client uses, especially as eric3 snapshots supports Qt4 and Qt3.

I just wanted to write that I did not find this. However, with try&error
I found that the directory containing the default DebugClient has
modules for the other ones to.

Could you include the same four Radiobuttons you have in the global
configuration in the project configuration? The same reason as above:
Clarification. Probably with a fith one that uses the global setting.

Just out of curiosity: What is the benefit of having a debugger that
already imported qt? Running small test scripts without the need to
import qt?
