Hide hard to understand warnings and error messages

[angelhof]

On my system hs always returns some warnings from try I think trying to remove some files that don't exist. Can we somehow redirect those to some log or hide them? If there are other hard to understand warnings we should remove them/hide them/or better explain them.
