The sakai property help.hide used to let you omit help for specific tools by adding the tool id to the property. It no longer functions this way, except for the tool id "sakai.help", which results in hiding all the help content.
Looking at the code, it appears that the sakai.help tool is loading the screensteps help HTML files for all the other tools through the "extraCollections" variable in HelpManagerImpl.registerStaticContent().
I can work on this issue, but I'm not sure how best to restructure things so that the tool id can again be used to omit the associated HTML files. If someone who worked on the original change to the help system in 10 can give me some guidance, that would be useful.
