Viewing post in Metadata encouragement
I am writing it here because not sure that I should open new topic...
I noticed that left bar "Filter Results" differs for games and assets
I found that assest's version has filtering by "tools and engines" but games's version lack this option.
If game's version has it, people will start accidentally use it. Some of them will start to think how to place their games there. Some of them will found metadata...
I guess you're right that many of these all control a kind of metadata. What I specifically wanted to do was change how link previews for the user appear. For individual games that's controlled under a widget that handles a bunch of metadata stuff (including a tab literally called "metadata") but there doesn't seem to be an equivalent for the user page.
