I've seen quite a few requests to allow the user to choose the first selected system. Unsure about how to implement that (i.e. need to think about that), but noted.
[As you've come to see the past few weeks, though, "noted" just means I've made a note of it and added it to a list of things to be done. Unfortunately I haven't been having any time to contribute to ES in terms of testing or developing recently, but hopefully when I have some more time I can pick up some of these things.]
