It would be fine if in go to type, file, symbol dialogs there waere a checkboxes that allow implicitly specify what kind of search user needs - regexp, camel case, case sensitive.
This would be more convenient for user and this would be also consistent with textual search in projects and files.
This will also allow to use full-fledged regular expressions, which is sometimes very useful.
Adding more options into search is wrong UI design.
Ideally the Go To will be just a line on a glass pane.
