Okay, I just discovered this morning when I tried to see how much space I would gain be emptying my recycle bin that the Status Bar no longer tells you the size of the files selected.... Also if you select a group of file types with various extensions you get a status bar like this....
Okay, I'll bite. clicks..."Show more details"
They could display anything here and it would be better than the date modified.
I noticed if the file extensions, (*.sys) for example, are all the same and you don't select too many you get a useful status bar
There has to be a config change to make this last screenshot the default for all regardless.
