I'd love the option, when djing with Ableton, to multiply the bpm of a clip by, for example, 3/4 or 4/3, or some custom fraction.
This is possible if there's only one warp marker and the tempo is consistent - you can just use a calculator and type in a new BPM. But in a complicated or older track with multiple warp markers, that doesn't work, it only changes one section.
