Fast, easy to use, but hidden contens is not shown

I had problems with a full Disk.
With Disk Expert, is was easy to find the biggest files.
Suddenly it happens, that with each deleted big file, the free disk space becomes less, not more.

It was caused by MobileBackups (local backup of time machine).

The hidden dirs on the root disk is neither counted nor shown by Disk Expert!

It would be nice to show the /.MobileBackups directory and other hidden contents.
At least their disk space should be counted and shown.

Nice is that the top twenty of big files are shown for each selected directory.
