I've found Switch (from
http://www.hfrmobile.com) to be an interesting replacement in the style of Switcher Bar. I've just given it a test and it has the usual problem with not being able to open while in the connections part of the WLAN utility but it does not block or change the "OK" button so it is less of a problem than with some of the alternatives. Just click "OK" and the menu works again.
I've found myself liking the minimise-rather-than-close idea, just to make better use of memory, but would like a better and more configurable option in a similar style to the switcher bar. I don't like the minimise button being changed as it seems to break some programs...
Anyone know of any better alternatives?
