Files types filter and Icons

[Said Bakr]

Hi, The resources browser should have the ability to filtrate files that it should display. The filtration may be restricted to the resources type of navigation, i.e. if you brows for images it should display images files only and so on. The filtration may be customized in the case of including the file browser as alone without the editor, for example, showing only HTML file in the case of using it to make link to an HTML file on the site.

In other word, what is occurred during the upload file should be occurred during browsing.

Another thing, It should be a way to add new icons for new files types. I don't mean changing the current icons assigned to already defined types.

As it is for the icon issue could you please open a new ticket for it?

Thanks
