Start a library for file system exploring and dialogues

[bvssvni]

It would be nice if you could get a dialogue for choosing or saving files or picking a folder. Maybe we could start a library for this using Conrod? Some features I would like to have:

• File extension filter (some default ones, like image formats supported by the image library)
• Supporting both dialogue and using it as a widget
• Custom panels for ad-hoc controls
• Browsing abstract file systems (custom file formats, databases etc.)
• Combine physical drives volumes with abstract drive volumes
• Default folder (give it an id to make it remember different default folders for different usage)
• File search
• In-dialogue drag & drop & rename
• Single select and multiple select (maybe a side panel for selected files from different folders)
• Event callbacks
• Path buttons (so you can go back with a single click)
• Image preview (why not?)
• Some modes specialized for image selection
• Image based search (there is a Rust library for this already)
• Integration with git?
• View/show hidden files and folders (files starting with dot)
• Cancel with Esc

Also, would be nice if folder names were hashed to make them slightly different in appearance. There is no point in using icons for folders when they all look the same.

Alternative is to use the native file dialogues like r3 does.

You are looking to implement a full blown file explorer there instead of a file picker. They are pretty similar so I guess it is better left out to be another project which can be used in conrod like other file dialogues including native ones.
