43things already has ajax-goodness tagging. Should Do This does not.
On top of this, when I click on Add tags, the cursor focus doesn’t go right to the tag textbox. I think that is actually more annoying than the non-ajax’d tagging, but they can probably both be rectified at the same time.
It would be nice, but it should be designed to fall back gracefully if the browser in use cannot do AJAX for whatever reason.
This is a problem for me when using All Consuming on my Palm PDA with the Blazer browser. Although the browser supports JavaScript, it does not support any AJAX trickery as far as I can tell. So while most of All Consuming is usable, the tagging feature is completely broken from my PDA’s perspective.
