Pinboard question

Is there a decent bookmarklet or Firefox extension out there? The official one doesn't work well for me. I don't care so much that it only shows my tags up to C or so (it is somewhat impractical to show thousands after all), but the field for tags is too limited in length, i.e. when I wanted to add another tag to a WIP I had previously tagged the entry field didn't even show all tags that were already on the bookmark. I could add another tag by entering it more near the beginning of the field instead of at the end and it still shows on the site okay, but that is inconvenient.

ETA: I now found this tutorial for making custom buttons, and that made a bookmarking popup with scrollbars and the entry field seems to work better too.
