OK, I look forward to the further improvements ;).

Regarding explaining the icons: the problem with doing it this way is that you only need to learn once, but with the popup you pay every time. That is why I suggested using tooltips: you can hover over and wait a bit longer if you are unsure. Maybe adding a word next to the icon and/or a legend in the side column is an option.

In any case, considering that you guys are both providing a free service and spending the effort to improve it, I shouldn’t whinge too much :).

The menu was a first-try at solving the problem that the icons don’t really explain what they’re doing very well: they look like they should be “digg/bury this entry” when they’re really “dig/bury this whole blog”. At least the DHTML menu explains what’s going on a little better.
