Too limited and does not remove all data on uninstall

The free version of this plugin is way too limited! I understand that everybody wants to make money but to find out if a plugin will meet my needs I need a little bit more to work with. That’s besideds the fact that the user interface to setup a poll is very confusing.

Lastly, when you uninstall the plugin it asks if you want to remove the plugin and all its data. Unfortunately it leaves the database cluttered with 9 wp_yoppoll_*database tables. That’s not what I understand under “remove all its data”!
