I don't have a mousewheel :-/ Click and drag would be fine, too. Or if the arrow keys did it, that'd be alright. Basically anything other than having to type a new tempo in.
Well then I'd definitely get something with a mousewheel on it. It's infinitely useful. By the way, check the Actions list. There are actions for increasing and decreasing current project tempo. Bind that to whatever keys you want.
It definitely has those options, but I don't like to turn them on because I end up accidentally scrolling randomly. It's not the biggest deal, but it'd be a nice feature, not much downside to adding it.
