Shimon's response to my question about 4Cast displaying more as a TodayPLUS plugin:
They can't right now, but I might add this feature on a later stage.
BTW, I've asked the developers, but I can't find anything to tell me how to use TodayPLUS. I can fiddle (as I have) but am reluctant to buy it unless I can get some form of integration between it, ZLauncher and 4Cast. I've also asked when the beta upgrade will go live.
