I envisage having a "Find All" button that is basically the same as the old Find In Project option, producing the results list in a virtual document as before.

@fafalone, if I add multi-line support to the Find/Replace panel, do you think that the Monaco inplace find/replace widget is really still needed? I'm trying to reduce and make find/replace more concise. We've currently got or had 4 different ways of doing find/replace so far (new Find/Replace panel, old Find In Project option, Monaco widget and Global Search addin).
