Decouple the "Folder preview"

> Edit > Settings > Preview > Folders > Show number of objects... (or similar, I
a have german version)

From the Folder properties dialog:

Right click on file > Properties

If you have disabled the "Show number of objects..." there will be no size of
the folder in properties dialog.

That's no good usability. You should decouple both so that you can disable the
"Show number of objects..." but still SHOW the size of the folder in properties
dialog. That's very annoying if you don't get the size and the number of
subfolders in the properties dialog!

I disabled the Preview of the numbers because it's VERY slow and you nearly
never need to know how many folders are in a subfolder. If you want to know that
you should "right click" > "properties" and get the numbers and the size of the
folder there.

With my suggestion you could solve too things once:

- speed up the navigation while browsing in folders very much
- get the size and the number of a folder in properties with disabled "Preview
folders"
