One feature that would be very useful would be to alter the "look" of a testcase/testsuite in the Navigator showing there are unsaved changes on a testcase/testsuite.
Presently there does not appear to be any discernible difference shown to let you know there are unsaved changes in a testcase or testsuite. Unfortunately I have fallen foul of this issue where my machine has lost power prior to me saving and I didn't appreciate how many unsaved changes I had in flight..... and by default the autosave feature isn't enabled.
