Hmm, a quick idea: Has anyone yet tried making an RSS feed of bookmarklets? I'd use it by dragging it to the Firefox bookmark toolbar to get a drop-down menu of usable bookmarklets, dynamically generated by an online app. In particular, say I had an outline in XoxoOutliner, and I wanted to treat the first level of items each as a loosely categorized inbox for ideas. The RSS feed would offer bookmarklets to append a new idea via quick pop-up to each of the top-level branches.
Not sure, but that's a great idea! The bookmarklets that load remote scripts and are therefore always up to date IMO are genius... this simply adds some depth to them I guess... and takes advantage of the Firefox UI.
Haven't tried it in FF 18.104.22.168, but older versions filtered out bookmarklets from the feed due to the JS.
