1/ The demo site is logged in with a default user account but the demo site itself does not save any data which is why you can't always proceed with "usual" functions on it. To access the ad edit screen though, a customer would select "My Dashboard" and then when their
list of ads appears, they select the pencil icon and the ad will open in the customers front-end user dashboard as per the screenshot below:
2/ There are no specific plans for this specifically at this time, so it would be something that you'd need to customize into the theme if you wish to implement it.
3/ This also would require customization of the default theme on your part
4/ Our themes are not encrypted, so you are free to make modifications if you like. There is some useful
documentation here with regards to customizations. In terms of the Photoshop .psd files, these are included with the developer license.
5/ Depending on how you wish to distinguish these ads from one another, it's again something that would likely involve customization. There are some great examples of ClassiPress sites which have been modified by our customers in the
AppThemes showcase. Thanks.
