> Why * * do we have to have a modal dialog to save a file when there's a perfectly good file manager?

At least for me, when I tried RiscOS, it was annoying and more work to have to switch to the file manager and then open more window(s) just to save a file. That could also be with RiscOS not having(?) Alt-Tab. I do sometimes use the macOS "proxy-icon" (which I think was disabled by default a few versions ago) to save/move files into finder windows if I already have them open.
