When a word is selected from auto-complete, it should submit the word immediately (whether clicking or hitting enter) rather than requiring an additional "enter" or click to submit the word
Page Alerts
Jessicar: Added a [legend] element to the special page and the helper dropdown. It needs some styles.
Title should be "Contributions from User: [username]"
Properties Panel
It shouldn't take 2 clicks to be able to add/edit/remove custom properties.
Guerric says: Why not? This is an advanced feature. Until there is a use-case where users need to interact with this commonly... this works.
Permissions Panel
Permissions doesn't show any warning when navigating away from it. It's not clear that changes will be lost if one does navigate away after adding a user to the grants list (since the grants list is not actually applied until the Save button is clicked).
There must be a way to navigate back to the page for which permissions where changed.
Guerric says: You can navigate back by hitting cancel. Maybe it could be reworded... but it's consistent with how we handle returns.
<ul> doesn't display bullet points next to list elements after saving a page
Log in/log out should not be a question (remove question mark)
Toggle links
make it more clear that "view article" and "talk page" is a toggle feature
table of contents -- it would be helpful if it said "show table of contents" and "hide table of contents" to imply some kind of ON/OFF thing
Comments
why is Edit a link and Delete a button?
fix spacing in the Files and Gallery sections
Flash uploader doesn't behave the same -- you must click "Select files" for the file dialog to appear (other skins it happens automatically)
Image Gallery
why a fixed width? I think it should stretch across the width of the page (I guess this is the norm for other skins as well...for some reason it bothers me)
Actions dropdown needs styling (remove bullet points, fix spacing between icons and text)
Files
extra column in the table? the first column is small, empty, and seems to have no purpose
tagging doesn't work
the data in the dark gray box is difficult to read -- the titles aren't distinguished enough from the data
separate into rows?
what is "what links here" ? is there a better word for that?
Dev blog suggestions
The two right columns are still in need of some organization...it's just too much for the eye to handle. I'd try to get it into one column. Or just block out that section completely so it appears to be one column (adding a border/light color behind the content).
Pick one of the two gray colors for titles. I don't really understand why there is a light gray and dark gray for the text. I'd stick with the red for the post titles and then a gray for the side content.
Make the subscribe links more visible. Bring them up to the top of the right-hand content or add an RSS icon (or both).
How about this for "Meet the Devs":
is it possible to have some additional info pop up when you hover over the name/avatar to display links like Twitter? like a speech bubble thing...
Increase the height of the horizontal line in the titles so it's the same height as the font
The super long search bar makes me feel anxious for some reason...shorten it.
