I think the OP has an excellent suggestion. I'd like better widget displays - the current "arrow to show more" method is lame... so far I have to click 4 times to go through all my widgets.
To each his/her own. I personally love dashboard and widgets. I use them dozens of times a day, every single day. I know many hate dashboard, but to me it's just so darn useful. I don't want to fire up an app for many of my tasks... I need to calculate something quick - just hit F12 or my mouse button, and there I've got my calculator (though Apple's calculator widget is lame as it doesn't have a "virtual tape", I use Pemdas). And so on for many widgets: note taking widget, task reminder, unit converter, iStat nano, iCrono, weather etc. Can't live without it.
Of course, I'd like the whole experience improved. I'd like an elegant way to allow a widget to float in the foreground/background, while I work away in non-dashboard mode... as is, right now when I use a widget I can't simultaneously work on another app. And so on. There is a ton of room for improvements, but the concept itself is great and a very welcome booster of productivity (at least to me).
