Just installed and I'm excited to give it a spin.
I did notice one minor issue - in the settings, specifically phrase option.svAttachmentsStripExif, the phrase text says "Strip JEPG EXIF"
It's pretty easy to fix on my end and doesn't impact functionality but I thought I'd at least let you know.
I've just installed this add-on as my site hosts some large files which some members have issues downloading due to time outs etc.
Regarding the resumable download option, do I need to do anything once installed? I've looked at the add-on settings and can't see anything.
