I'm not sure if this is at all possible and I have tried searching but to no avail.
I would like to know whether the following is possible:
- Restrict Roles from seeing each others images in the media library in Add New Post/Edit Post > "Add an Image".
- Disabling the video and music upload
- Restrict Roles from seeing other posts but their own in Dashboard.
The above is for the backend of the site and not the front-end.
I would very much appreciate if anyone can help. Whether there are any plugins that may help me accomplish this.
Thank you in advance
