I’ve been lamenting the loss of Shiftspace silently and sullenly ever since I upgraded to the beta versions of Firefox 3 last year. I really didn’t want to downgrade and wait, though, since I was experiencing a few unhappy issues with Firefox 2 on Mac OS which happily disappeared with version 3. So, I did without Shiftspace, cool though it may be.
No longer: there is a version of Shiftspace available which works with Firefox 3.0… you can find it here; you will want to click on the “release userscript” in the bottom right-ish corner.
Should I add you’ll need Greasemonkey, first? Well, I guess I have, now.
While searching for this, I happened upon an app called Lily, which is a visual programming environment written in Javascript:
Lily is a browser-based, visual programming environment that lets people create programs graphically, without writing code, by drawing connections between data, images, sounds, text and graphics. Lily’s cross-platform, free, open source and is written in JavaScript. Did we mention it’s fun?
What does it all mean? I don’t know! Isn’t “it’s fun” enough for you?
