One of the reasons why this was suggested, was that ;
when the user is reviewing all of their plugins (which ones they’ll keep or dump, or why do they still want them), they will need to cover the entire list.
They need to know that they have looked at each plugin and decided to keep (and possibly adjust which group[s] they want to have it included in.)
The the full list acts as a complete check list.
But in looking at the whole list, they need to go up and down to see what the other plugins in the same group are.
So if the plugins are displayed in order of groups (with duplicates being shown in each group – possibly some sort of visual note that it already is in a group higher up the list), then all plugins related to a group can be seen at once.
It would also be handy to attach notes to plugins, and to attach flags to plugins. The user could assign the purpose of the flags, such as mark to keep/dump/yet to review/seems troublesome/checks out well-send approval message to plugin site/etc.
