First off I'd like to say thank you for using Simply Poll, it's great a little project I did in my spare time being used by lots of different people around the world. I'd also like to apologise for the lack of updates in regards to the plugin, the main reason being the slow down to Christmas and then having a break away from the computer for a week. But I'm back now and working on the next update of Simply Poll.
Most of the issues reported I believe should be fixed in version 1.4, as well as some improvements made to the code base to allow easier editing the plugin. This is also the start of a move to Simply Poll version 2.
Simply Poll v2 will include proper support for features such as theming, better admin interface, custom text, import/export options and the removal of limited number of poll questions! If you have any other request you like to be added to Simply Poll v2 then please let me know and I'll try my best to get it included in the new version.
