ClassiPress, like all of our themes is not encrypted, so essentially you are free to customize it as you wish. We have some
documentation here with regards to customization of our themes which will give you an idea of what is involved. So, in saying this, questions regarding customizations in terms of "can we..." are technically yes. To address your questions not specifically relating to whether or not you can do customizations:
1. There is no setting in the admin dashboard to change the default radius, so yes this would require customization.
2. Yes, our themes are well coded and commented
3. Yes, this would require custom coding
4. If you use the custom form function and build forms without the location fields, then the map will not appear in the ad sidebar by default.
5. You set the max file size in the
ClassiPress admin dashboard and if the customer tried to upload a larger size, they will receive an on screen notification of the limit.
6. You can find
additional payment gateway plugins in the AppThemes marketplace, but not the one you mention
7. No, but you can find other developer information on our
AppThemes developer center page.
8. AppThemes does not officially support customizations or third party plugins, so if you are planning to seek support for these then it is outside the scope of the support we offer and is subject only to community based support. The initial purchase includes 12 months of theme updates and access to the support forums. Thanks.
