Another row of favorites/shortcut buttons for samples?

I use Renoise for both music and sound design purposes, and it would ease my work a bit if I could just have more sample folder shortcuts, since it would allow for more distribution by sample type (drums, tonal stuff, stuff recorded by me, different sample libraries…). With the fairly small area where the folders are displayed it can be a bit of a chore to navigate folders which have a large amount of subfolders in them.

Yeah I see it, but still, more shortcut keys would be handy, especially since where they reside there clearly is room for at least one row more without sacrificing room from something else.
