Fader fine adjustment & alternative waveform view

I like chopping with the S2400, but if samples are a couple of bars long it’s hard to be precise with the faders.

First request:
Is it possible to press shift (or another key) to enable fine adjustment with the fader? To make it useful, the fine adjustment would probably need to centre the fader and then you’d need to catch it up.

Second request:
Can there be a setting in the waveform view to show all start/end points? It would be too busy to show all of them at once but it would be nice to see the start/end point of the last moved fader on the screen with the same F keys as in slice mode.
