Top-Level projects can be hidden from the Projects View by configuring the ACL OpenProject denied on those projects and activate si.default.filterTopLevelProjects in the si.properties file.
Some users also wish to hide subprojects in the Project View if the ACL OpenProject denied is set for those specific subprojects.
It should be possible to have the same configuration for subprojects too by introducing an additional property like si.default.filterSubProjects in the si.properties file.
