Templates - hide/unhide default templates + add tags and/or a search field

There are too many default templates users do not need after they have selected the ones they want to use. It would be useful to have the possibility to hide the default templates not needed to find your way around them more quickly. Or, just like with workflow templates perhaps, to have the ability to add tags to templates, and be then able to search for them via a search box. The idea is for users to find the templates they are looking for more quickly
