Disable scroll bar when apps exceed taskbar size (allow smaller icons+labels or more rows)

I am currently using the task bar vertically, but it bothered me horizontally to, I'd love for that pesky scroll bar to disappear (the one that when you open 1 extra app than space required and boom, 10 apps here, 1 app there) .

Anyway: dynanic icon size based on a max(normal icon size, taskbar / num apps open)

Or another awesome thing is to allow multi row taskbars like the horizontal.
