MatchTool deserves a button to apply a search

[Ducasse]

Right now we can enter an expression and select a class
and we see the result.
But I cannot just change the expression and see the result.
We have to reselect the class.

Could be this included in the new Method Finder as a new Expression search type?
Then we could browse results from there, senders, implementors, etc.

[Ducasse]

Potentially yes.

This is because the "Occurrences matches" is a separate tool. We could improve the expression finder to update automatically when typing. But, this can be really slow as if one search the occurrences in several classes, it can take minutes. Other option can be to add another button like "search in previously selected class" but I that can pollute the UI. Already the button "Search on selected classes" remembers the previously selected class
