Hi Adam, I just migrated our main product to Django 1.4 and will be able to have a look at your CSS changes soon, thanks a lot for the changes! I'm fine with having the new version work with the latest stable of Grapelli and will mention the last working version for 2.3 in the readme file.
I also updated jquery-autosuggest to 1.6.2 (from 1.4).
This fixes a bug where you type a partial name "aw" and you then you arrow down to "awesome" and press tab to select awesome. You actually would then receive "aw" and "awesome" as tags. This is now fixed.
