load / save routines speed

Is it possible to 'slow down' the speed of loading (saving) from divIDE ? I think the 'jump' from about 5 minutes (tape) to almost instantaneous (divIDE) loading time is a bit too much...

To me, 5 to 10 seconds loading a 48k code would feel much better. And some border colour changing would be nice during this time... I think it should easily be done by inserting some delay routine after every byte sent.

Or an user selectable speed, maybe ?
