File column in a table - additional options

Suggestion Box
1

Many times when creating a file column type in a table there are options I would like to set, that are not present today.

  1. Limit the number of files allowed uploaded.
    Sometimes you only want to allow 1 file, sometimes 2 or whatever number suits you best. Being able to put a limit would be very useful.

  2. Limit the filetypes accepted.
    You don’t want users to upload completely random files. If it’s a document that needs to be uploaded, then being able to specify what kind of file extensions are allowed would be awesome.

  3. Automatic preview of uploaded file.
    This would be a nice addition.

  4. Automatic available link to the file (using formula to get the url) without packs would be nice as well. this way, you could use a formula for retreaving both the link and a preview.

This is what I have for now. Please consider this.
