Display progress reporter for plug-ins that are executing with the DOWNLOAD_IMMEDIATELY option
In the current implementation a window with the message
Do not close this window until the download has finished. and a
Cancel button is the only thing that is shown. It can be hard to know when the download has finished. The "Cancel" button closes the window, but it doesn't abort the download. If it is possible, it would be nice to have an
Abort button that really works.
