Would it be possible to save the result of the run to a file that can be displayed with the same user interface (like how atop does it) ? My runs take quite a long time and I lose the whole session when I leave. I know the results would not be live but it would still be a lot of help identifying large files and directories (which I can double check manually) especially on a slow moving server.
(I do not strictly need this but I am posting it as a nice feature to have depending on the scope you have in mind)
