Diaa :

Is there somewhere to post bugs or feature requests for the discussion system?

Yes, use bugzilla, assign it to the product “MediaWiki extensions”, component “LiquidThreads”.

Here’s a handy link to do that: http://bit.ly/2y8Dz

Nemo :

It should be possible for editors to edit/move/delete/split/refactor messages or threads as a whole (e.g. vandalic ones).

It’s easy to edit messages, move them between discussion pages, and delete them. I’m working on the ability to split messages between discussion pages.

jps :

Can you collapse threads? Really need that because too many people are collapse-box crazed, usually for pretty poor reasons having very little to do with improving the quality of the ‘pedia. But if you make it an option for the end user to collapse threads on demand we might be able to have some progress.

Great idea, I’ll add that in…

penubag :

One question/request:
Can the quoted text be a grey or light color?
This will make it look less cluttered and help find the actual content.
If users have a short reply, the quoted text gets too much in the way.

We’re looking at making the quoting optional, and visually distinguished from the rest of the post.
