Hello!
I'm working on a project to integrate Etherpad Lite with MediaWiki. So far, it's been going swimmingly. One of the first steps was to make a plugin that allowed the user to insert wikitext-like formatting (a la WikiEditor or the default edit page).
I've gotten my etherpad-lite plugin working now, it's performing well with links, headlines, formatting....all without extra API calls or hackish methods. However, many of the buttons are currently empty or using the "default" icon for italics.
I could try to reuse either the buttons from the existing edit form, or from WikiEditor, but they need to be 16px square, as opposed to the 22px square of the existing icons. It might be good to also change the color scheme to fit the different UI of Etherpad, as opposed to the WikiEditor UI.
If anyone on this list is available, I'd like them to take a look at it and make some icons that make sense. Here's the current information about the extension: http://lists.wikimedia.org/pipermail/wikitech-l/2012-June/061265.html
You can also find it at https://www.mediawiki.org/wiki/Extension:EtherEditor, though that page has less information currently.
Once you get to the editor itself, like I said, the buttons won't have anything helpful inside of them--but the titles are all correct, so hover over a button to see what it does reliably.
Thanks so much for the help!
