Minify v2 is coming along, but it’s time to start getting some real-world testing, so last night I started serving this site’s Javascript and CSS (at least the 6 files in my WordPress templates) via a recent Minify snapshot.

popWin = open(url, name, features, replace);

In the redundancy file. Someone needs to create a bookmarklet that loads into the current page an interface for executing pre-saved bookmarklets. I’ve already seen several examples of this with pre-defined sets of bookmarklets (notably Favelet Suite) but why limit the user to one set? I’m already keeping my regular bookmarks and [...]
