that's really nice to hear! :)

Regarding without GUIs: Since my last patch (which was pushed by Jordi
recently), there's a function 'profshow' which can be used to print out
the "hottest" functions in a table.

Maybe you already used this function and don't regard it as a real
"GUI", but at least you don't have to work through the structure array
any longer and get the data already sorted.

Cheers,
Daniel
