for example, what if we want to merge x collections within a project. If regex search functionality also worked, that would be great.

The onclick methods are named select_all_files() and unselect_all_files(), however they are not selecting files. Please rename.

Could we make the select_all and unselect_all methods generic, move them into assets/javascript, and use the same method for both the collections and projects page? For example:

function select_all_items(selector) {
  $(selector).find(":checkbox").filter(":visible").prop("checked", true).trigger("change");
}

<button id="select-all" type="button" class="btn btn-default" onClick="select_all_files('.arv-project-contents')">Select all</button>

Peter: yes, moving into js and reusing this code is a good idea. Updated accordingly. Thanks.
