One of the things I love in Ableton’s Live is the ability to change the tempo without having to deal with a dialog box. In Live a user has two options for changing the tempo.
1. You can click on that area and type in your new bpm.
2. You can left-click that area and scroll your moues which dials in the new tempo.
In both cases the effects of the change area realized immediately.
How Podium handles it now is ok, but I think this improvement makes things a lot smoother than having boxes pop-up in the editor.
