I was afraid that was going to be the answer.
The problem is that after just a few times of using the GUI, clicking
through those dialogs becomes automatic while remaining annoying. And
that means they aren't protecting/helping any more.
For more details on why confirmation dialogs don't help when they are
pervasive, see:
http://www.asktog.com/columns/069ScottAdamsMeltdown.html
(specifically "Error Four: Confirmation Substituted for Undo")
and:
http://books.google.com/books?id=04cFCVXC_AUC&pg=PA67&lpg=PA67&dq=confirmation+dialog+considered+bad&source=bl&ots=jfwiT8n5sP&sig=YKxvd_HWhSfOGpXI3jx2eTJqsrs&hl=en&ei=UYK8ScKOApiWMfqCzZcI&sa=X&oi=book_result&resnum=2&ct=result#PPA67,M1
THg's dialogs are inconsistent. (I am not going to make a laundry list
here, these are just some examples)
The synch dialog box gets this right, the results of the incoming/
outgoing/push/pull commands are always just there, no annoying
separate dialogs with the results, just there.
The history/log viewer has some sub dialogs (for checking out
different changesets) that are annoying.
I was serious when I said that good design is hard. Hopefully the GSoC
this year and perhaps some of my own feeble efforts can try to remove
the inconsistencies and annoyances (so long as the actual risk of
mistakes doesn't get worse).
