Hi Soren and Jason,
At the moment there is no way to reorder the fields if you are using the form results by default, but you can go to Settings > Email Notices > Notification Message > Configure Email Message, remove [form_results] and insert the fields from the "Insert data from:" drop-down in the order you want. However, I will pass this suggestion to our developers to see if it is possible to reorder the fields automatically.
About the text area problem, I have reproduced and I have already logged it to be fixed as soon as possible.
The width of the submit button can't be modified right now, but this is going to be added in a update.
The number was not thought to be used to enter telephone numbers, since we are going to include a specific field that is going to be used for this purpose. I am going to ask our developers if we could increase the maximum number until this magic field is ready.
The width of the fields is limited by the width of the form right now. It is set to 200 because a smaller form will be tiny. However, you can change the width or the space between the fields if you do it manually performing an Automated Export and editing the default.css file so you can adjust the theme as you wish.
