Currently when selecting samples for a kit, each time one goes to the next instrument, the file browser takes you to the previous location, e.g. when selecting the snare sample one is taken back to the kick folder and then needs to navigate out and around to the snares.
My suggestion is that each row of a kit instrument causes the sample browser to default to the same folder from which that row is already addressing a sample.
There could also be standard defaults such as bottom row always defaults to the kick directory, second to snare, third to hihat, etc.
And in case people have reorganized their libraries, kit tracks will automatically go to last used directory for that row, as to make the defaults adaptable to the user.
