As an addition to the bug fixes in the editor, that I think absolutely imperative for IPB's future, I'd just like to suggest two minor suggestions that my users asked me.
1. The ability for people to save directly their messages, as an addition to the auto save that is made. What I would actually like (if it's not already possible) is that users be able to click on a "save" button so that their posts can be saved in the database until they are submitted. Exactly as the auto-save, but adding a manual ability to do that.
2. The possibility, when using the plain text editor, to still click on the BBCode buttons, in order to use BBCode. For the moment, when we're typing text within IPB's plain text editor, we have to add manually the BBCode tags. What I would like would be the ability for my users to highline their text, for example, an then (to quote an example that my users brang to me) to click on the "center" button, so that the opening and closing center tags appear directly in the message, surrounding the text that has been highlined.
I hope my two suggestions are comprehensible enough, as I'm not a native english speaker.
