I'm a mac newbie coming from linux. In order to not have all applications in the /Applications top folder, I create some empty folders in the /Applications folder and move apps there (to group apps). Reflections/questions: It seems to be ok for me to create folders in /Applications that are owned by me without giving a password, which seems a little bit funny. (/Applications belong to the admin group as also I am in and admin group can write in /Applications. In Linux I have to to "sudo mkdir" to make folders in the corresponding folders). Is there any problem with moving apps (owned by root) into these new folders that are owned by me?
