Thanks for this useful & simple plugin. I have few notes that would make this plugin perfect (at least for me):
1- Adding the ability to search in the poll's logs depending on any criteria (user, answer mainly). This does exist as a drop down list, it's nice for an answer option but for users it's not specially when I have about 6000 users on my site. so using a classic search with a text field will be more useful in this case.
2- Adding the ability to export logs to a file (excel for example) to be able to deal with and analyze the results.
3- Show statistics report for a poll, just like the one appears in the front end after voting.
4- Adding "Other" option to question type (this might be useful in some cases)
5- organizing polls in a better looking way in Archive page.
Thanks for your work.
