Salesforce file import — File import modal for a Salesforce add-on

A file import library for a Salesforce add-on. The modal does two jobs: bring in new files and pick from the ones already uploaded.

The drop zone sits on top, with an Upload manually button for anyone who’d rather browse and an info link listing the supported formats. Below, uploaded files are sorted by most recent, each with a file-type icon, its size, who uploaded it and a Select action. A file still uploading stays at the top of the list with a progress bar, so the rest of the library stays usable while it finishes.
