I disagree. Just force an interactive choice feels a lot better to me (and far simpler). Otherwise you'll see people jokeying for order for their tool, and anyway you have to provide a user setting. A cool one: open the settings browser at the right place, instead of creating an ad-hoc dialog. Reuse code + GUI familiarity + less lines of code. There is apparently some magic in the world menu to trigger a user-driven choice among existing tools, but I don't know how to trigger that. No, the only thing it does is to execute all the methods (in a some > un-defined order).

I'll have a look. I noticed that unloading AltBrowser was a very nice way to end up with a dead Pharo image :( Remember, AltBrowser is clearly the best, so I won't provide a way back to the old ways :):):) Thierry > > > Marcus > >
