Grouping of download queue and/or bookmarks

[fusedragon]

I ended up having a few thousand mangas in my queue/bookmarks, would be nice to have a grouping feature. Would work like creating a folder to drag stuff in. For bookmarks you could then right click on the group and check chapters for mangas in the group. For download queue you could expand/collapse to declutter the queue, and move groups like you would individual manga.

For example I might create a group of my top favorites that I might check for updates on a daily basis, instead of checking for a few thousand. They might be from different sites so filtering by site wouldn't help. Or I might separate weekly manga from monthly so they can be checked at different frequencies.
