I don't know how useful this request is relating to the Maven toggle tests button is.
Currently, if I enable "Toggle Skip Tests Mode" in the Maven Projects window, it skips tests as expected if I run the various lifecycles. It has the step "test" struck out as a visual clue to that.
My request, even with "Toggle Skip Tests Mode" enabled, if I explicitly double click on the "test" step, it should run the test phase. Adding this feature allows me to skip tests in the overall maven lifecycles as well as letting me execute maven tests whenever I want without concerns to the toggle button.
