Could you suggest what information would help you make a better choice?
Would it be enough to have the ability to disable listing “not installed” macros (see How to disable installation of new macros from WYSIWYG?) or do you like that feature but would like to see some other ways of differentiating the macros (and in this case, which ways)?
Thank you
PS: You can hide some macros already using https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Configuration/#HMacroscategoriesandvisibility
