Great plugin, but am I able to remove the ul and li tags from around the tweets? I see it's hard-coded into the plugin, and I don't want to hack the core files. I'd really appreciate having just a bare-bones output that I can style more freely with css. Currently the ul and li tags are causing me issues.
I'd prefer using the widget declaration in the functions.php file to add the ul and li tags when necessary, rather than force them into every instance of the widget.
