Hello,
for 1) please refer to the configuration section of the documentation. It will tell you what works for which animation. You are experiencing 'normal' behavior for the animation you have selected.
2) you probably need some CSS tweaking. Animations usually require a specific width for items, that is why it does not take the whole space. I would suggest you try one of the downloadable animations that will give you more options.
3) you are right, the item width should be 100%. But since you are using animations, the whole space taken is 'items width'.

Finally, I understand there are a lot of options and it is a lot to 'digest' and yes, it is overwhelming. The really most important info you need is the configuration section of the documentation when you are using animations.
If you cannot make the module work the way you need to, please send me your login/pwd info, the URL of your site, what you wish to accomplish and I will be happy to set it up for you. Please send your request to [email protected]. I never meant to make people pay for an unusable module, it is just highly sophisticated to allow for maximum flexibility and cover most needs with such a module.

No problem!

No need to apologize, of course

This is rather strange behavior, it should all work or nothing work... Maybe you discovered a bug, I am going to take a look with the credentials you gave me previously.
