Recent mention of the profiler prodded me to take a look at the profiler in 1.3. Very nice! Some "quick" changes that I think would be good: (1) Shout in the code pane; (2) Use tabs to show the gc data or the code; (3) Add a tab to show the result rather than using a modal notifier (which probably quickly gets dismissed, and then missed<g>). A non-quick change, if it's even possible... Some of the slickest Dolphin goodies in existence include: Ian Bartholomew's ChunkBrowser (Pharo's lost changes is close and useful, but not the same) and Profiler, the SUnitBrowser (nicer than the SUnit test runner), and Ghoul. Ghoul is well named. It presents Dolphin crash dumps in a debugger-like view: http://metagnostic.org/DolphinSmalltalk/Ghoul.html If there is, or could/should be enough data in a profile to do the same thing, it would make an interesting addition. Then interacting with the code includes the ability to see the values of variables. Bill
