My understanding is that the OB tool set is the presumptive choice for Pharo - unless I'm wrong, that makes this a Pharo related topic, if only to reopen the choice in light of your position.
I don't know which is the official Pharo image? There is a plain one without any extras loaded that the Pharo team uses for their releases, and then there is one with additional tools loaded by Damien that also contains OB-Tools.
Do as you want, but Object Arts had this idea and very quickly decided the simpler notifier had a very essential role. They left the option, activated the notifier by default, and strongly warned against deactivating it. That was based on being bitten by the kinds of concerns I have documented here.
Don't get me wrong. Feel free to add this preference and the additional dialog, but don't expect me to do it: http://mail.wiresong.ca/pipermail/ob-dev/2008-August/000580.html Lukas -- Lukas Renggli http://www.lukas-renggli.ch
