Ability to import multiple samples to multiple pads at once
This would be a significant time saver for me.
When I select multiple files in the file browser, I'd expect that dragging the selection over a bank would auto-populate multiple pads at once. However that's not the case, only a single file out of that selection is applied to a single pad.
Besides the "Load sample" button in the footer, maybe a "Load samples to pads" would appear in its place when there's a multi-selection going on in the file browser.
Now, I think there might be some UX to consider here: you probably don't want to overwrite existing pads when dragging. So how about populating empty pads in order?
