In answer to your questions:
- Yes, custom forms for job submission is implemented in JobRoller v1.7. Currently the beta version is available to existing customers, but until the official release, the demo site is not yet updated to this version.
- This is not a default function of the theme, with the only option being to upload a logo image for the listing. The custom form builder in v1.7 will allow users to attach a document (e.g. .pdf or .doc), but this appears as an attachment as opposed to a gallery. So basically what I'm saying is that it would require customization on your part if you were looking to add this feature. Thanks.
