After install Qt Designer, if you want to use the help system, you're stuck unless you install one more package through Synaptic: Qt Assistant. However, there is no stand-alone for this program. It is bundled in the dev tools. Making it stand-alone is a valid request to the dev team for the Qt suite of packages. At the very least, if Qt Assistant is not made standalone then it should be a dependent of Qt Designer. Otherwise, if Qt Assistant isn't pulled from the qt4-dev-tools package, then Qt Designer should *REQUIRE* qt4-dev-tools as a dependant. Otherwise, users will install Qt Designer and not have any way of figuring out why they don't have help menu options available once installed. As a workaround, users who have installed Qt Designer must then install (through Synaptic Package Manager) "qt4-dev-tools". That also adds a bunch of stuff they don't need, but at least they can then use the help system for Qt Designer. Here's a link to this bug.
