If you feel there is an interesting feature missing in CKFinder, go to the community forum and share your idea! We are really committed to making CKFinder a versatile and flexible tool, so we are looking forward to your input.
It is also recommended to begin with a search at the community forum to see whether the proposed functionality has not been implemented yet and offered as a plugin or code sample. You can also start a discussion to see whether the proposed feature could gain some interest from other community members.
When submitting your idea, feel free to attach your code suggestions or patches that can serve as a prototype for the requested feature. A good idea is to provide a screenshot or screen mockup showing the idea — this is particularly useful in all cases related to the application interface.
