Hi there, thanks for the update. I have seen the screenshots and got it working this way. Here are two specific suggestions that I hope are not too difficult for you to implement:
1. Make the multiple downloads scenario work just like the single download — i.e. multiple inline links without the need to check boxes. This would be more helpful I think for many use cases.
2. Support the Download Monitor (DM) custom formats for the inline links. This should be possible to do if you can pass the DM shortcodes, which are well designed. Essentially Email before download would act as a wrapper around Download Monitor, asking for an email before the download but otherwise using all relevant DM settings, including (custom) formats.
(Well, at least the first should not be too difficult…)
