I've noticed recently that when I try to view all posts by a user, I only see the last twenty, even for myself. There's no see more button or anything, it just stops at twenty posts, when previously it used to load more as you scrolled down. As an admin, I find it useful to see a user's post history when dealing with issues. And as a poster, I find it useful to find my old posts.
Unrelated, is there a search function planned for discussions? I often see threads similar to older ones and I want to find the old thread because they often contain insights useful to new discussion. But since most posts are poorly tagged and uncategorized, scrolling down is the only option which is too cumbersome for a community with hundreds of posts.
My biggest problem with Discussions since it was converted to Feeds is when I accidentally clicked right next to my unfinished post that I'd written up, it caused the editor box to refresh. It caused me to lose all my work with no chance of getting it back. I didn't have the patience to rewrite it from scratch until the following day.
Another thing that I would like to see is to have the Discussions Guidelines converted so that it is editable in Feeds form. Since Feeds supports internal style links, whereas Discussions on its own only supports https: links that can't be made to resemble internal style links.
I wanted to add links to the Guidelines of some of the wikis I administrate so that they have a more furnished feel, like forum threads used to have, since forum threads supported internal style links, as well as wikitext which won't be rolled out to Discussions anytime soon, if at all. But if I could just have the internal style links like I do with feeds, then that would go a long way for me.
But I still need to be careful because it's still possible for me to accidentally delete all the text I've written while trying to delete most - but not all - of the text that I've written up, while clearing text that I don't intend on publishing. But thankfully I am still able to hit the undo button when that happens. Editing discussions posts since feeds were rolled out hasn't been nearly as smooth as I remember.
