Hi @dlandon,
First, thank you for this plugin, to me is a must have, just in case someone, or myself, delete somethink we don't want to.
Said that, and let me tell you that a I didn't read all pages of this thread, there are a few ..., there is a possibility to avoid that any user that have access to the share, delete files inside the bin? Only be able to see what inside (Read Only). An to delete the files do it from the plugin.
This is to avoid that someone, with no good intentions, to delete some file completely, this functionality was used by my older NAS, a synology (bye bye forever, right now I hate that type of NAS, they are so bad compared to something like Unraid...), and was pretty useful and give higher security if the intention is to protect files from shares from unauthorized users that somehow access the share.
Of course this is just an idea to further improve your plugin, it's ok if you see this idea a pain is the ... :P.
Let me know your thoughts about this.
Regards
