No, I wondered why it should. I don't want a mail-sending IDE.

No, I mean that you can communicate to GPS from your Ada program, e.g.
while debugging it.

gdb is garbage. But even if there were a decent debugger for GNAT, you may
want to have some tracing tool. GPS gives you an opportunity to browse the
sources while tracing.

I am not sure how it can be faster than in GPS: F4, shift+F2. Debugging
GtkAda with gdb cannot work, because GTK does not use exceptions to
indicate errors. Also if you stop GTK in an unfortunate state, you would
corrupt GUI in a way unrelated to the original problem. It is similar to
real-time applications, which break when stepped. Tracing works much better
and an ability to ask GPS to show the source where the message came from is
a great help.
