Vital Shortcuts

[ono]

I just want to reming some easy vital shortcuts that would make FL much better I've proposed on blog.

⌥⌘←/→ Open focused folder in opposite (selected by arrow) pane
⌥1…9 Sort using field, Opt+1 for name, Opt+1 again for name desc, Opt+3 for size, etc.
⌥⌘C Copy selected file path (hell useful)
⌥⌘S Calculate size of all folders in the list
⇧⌘T Open current folder in terminal

[ono]

Any change for such shortcuts? I think they don't need much coding, but would help really really a lot...
I've already bought the license, but I'd donate this feature if it was possible :/
