Can I set ctrl+s and ctrl+o window size & ctrl+o save as type defa

[Moonbarker Osbourne]

My browser is Opera. When I posted to the official user forum asking how to
set the ctrl+o and ctrl+s windows to the size and position they were the last
time I used it even after a system restart, an expert told me "I assume
you're using Microsoft Windows. Unfortunately, the open/save common dialog
box is handled through the GetOpenFileName/SaveOpenFileName API"

So if it is a Windows issue, how do I set it like how I want it?

Also, while I'm posting here anyway, is there a way to get the ctrl+o "save
as type" to default to "all files" instead of "html files"

provided the third party software supports it, Windows will reopen a
program at the same size and location as it was closed at. If "opera"
doesn't support it, it won't happen.
