Proposal:
I would like to have an automatic behavior (like within WIKIPEDIA) to show a summary/abstract if you hover a wiki link with the mouse.
Just pulling out of a hat: an implementation could check the presence of a new standard wiki object (something similiear to “XWikiComments”). As each wiki link is checked if the target is present the overhead wouldn’t be to much. The summary content could be delivered by a new document tab and/or something like a macro (e.g. {{summary}}).
(For the future: A summary could generated automatically by A.I.)
Opinions ?
