Hi
I suggest that the “open song” dialog (and similar, disk browsing selectors):
- jump to the first folder/file that matches what’s typed
- backspace is used as jump up one level in the directory hiarcy
This is inspired by at least thunar (see attached video) file manager under linux, but I believe this to be pretty standard, I think all linux software that uses gtk file selector works like this…
