And now that I’m thinking about it I think that some of the functions that the major plugins offer ought to be offered along with the cms. Not as features of the individual themes but as part of the cms.
I use for instance a plugin for the lightbox, a plugin for disabling the right click on images ( who doesn’t disable the copy paste of images? ) another one to block pinterest, a plugin to block unwanted ips etc.
These features should exist as part of the cms by the time that the majority of users need these features and get them with the plugins. These are very basic things.
