Found out the original program was no longer being worked on and found this fork. I would love if the following could be added/adjusted in the future.

1. Disable the ability for main group tags to be automatically added when tagging with a sub-tag. I organise my tags into groups, so, I have a tag named "Artist" and in there have a tags of artists names. However, when I tag an image with an artists name it adds the main "Artist" tag as well. I find this to be very redundant and clutters the tags.

2. Add the option to have "Inherit Parent Color" always be enabled when creating new tags.

3. Add the ability to auto-assign tags relative to the folder. For example I have a folder of a particular artist I want to be able to select tags that get auto-assigned to every image within that folder. Naturally I want every new image added in to that folder to be auto-assigned with those selected tags also.

4. Be able to remove broken images. I use another program to detect duplicate images and when I delete them they break in Allusion however I can't remove those broken images from cluttering the feed.

That's about all I think about at the moment as I've been trying to get a hang of using it.
