Guille: I developed a couple of tools that may help you.

The first one is a tool to discover the classes that were used for a particular time duration or block. 
http://www.squeaksource.com/ClaseUseDiscovery
You should read: http://forum.world.st/ANN-ClaseUseDiscovery-tool-tp1296859p1296859.html

On the other hand, you can also try to replace each CompiledMethod of Morphic by a MethodWrapper that just logs its name or something like that. Then you can know which methods were executed.
In the dev image 1.1 there is already the package MethodsWrapper from the repository: http://www.squeaksource.com/ObjectMetaTools

In the package ObjectMetaTools of the same repository, you have ProtocolCatcher. Check its class comment.

Finally, I think a very good idea is to use Adrian Lienchard� DTrace integration to the VM: http://forum.world.st/ANN-DTrace-for-Squeak-Pharo-td2173422.html#a2173422

So...what I am saying with all these is that probably, search senders is not enough to clean Mprhic, as Levente said. I would take a dev image, and I would load big projects, like Moose (complete complete), Dr Geo2, etc, and I would use the tools, run all the tests, and check on runtime what is being really used.

Good luck

Mariano

Hi
I got a flu last week. :)

Now how to proceed: step by step :)
Start little do it often.
So what I suggest is that you go one fix at a time, you send it to the list, open a ticket, people get a chance to argue
and we loop million of times.

For example
� � � �- I would like to understand if they are not things to be changed now that we have true bloclosure - for menu opening...
like PluggableXXXX and fix that
� � � �- I would like to have less subclass of StringHolder :)
� � � �- Something good would be to check the fix Juan did in CUIS for the scrollbars and friends.

Yes cleaning morphic is important.
