another feature request

[muh muh]

I posted this in krusader-users, but then I found feature requests here, I so am posting it here, too, with some clarifications.

In the file list panel, I noticed that the menu option Edit>Calculate Occupied Space when used on directories works very quickly, even on large directories! This is great!

My request is:

Provide an option to automatically Calculate Occupied Space on directories in the file list panel. The number could  be displayed in red until the occupied space is finished being calculated, to notify the user in case a directory is taking a long time (although I have not yet encountered this). Also, right-clicking on the size value, when red, would allow the user to "Stop calculating", just in case. A general "Stop calculating" for all directories at once would also be useful.
