How can I search on the hidden text attribute?

Just upgraded to LibreOffice 4.3.5.2.

I would like to make LibreOffice one of my writing tools. Currently I heavily use hidden text in MS word for notes, then for the final draft I delete all the hidden text.

In MS Word, I can go into Find & Replace, click Font, and Hidden is one of the attributes I can search on. But the option to search on hidden text doesn’t show up in LibreOffice.

Install
AlternateSearc&Replace_writer

Work with CharacterStyles instead of Direct-Formatting

AltSearch has Property to search for CharacterStyles by StyleName.
