Once you are comfortable with manually setting tags and ratings, you may be interested in setting some shortcuts to do it quicker. Try hitting file->shortcuts or clicking the keyboard icon on any media viewer window's top hover window.
There are two kinds of shortcuts in the program--reserved, which have fixed names, are undeletable, and are always active in certain contexts (related to their name), and custom, which you create and name and edit and are only active in a media viewer when you want them to. You can redefine some simple shortcut commands, but most importantly, you can create shortcuts for adding/removing a tag or setting/unsetting a rating.
Use the same 'keyboard' icon to set the current and default custom shortcuts.
-system:similar_to lets you run the duplicates processing page's searches manually. You can either insert the hash and hamming distance manually, or you can launch these searches automatically from the thumbnail right-click->find similar files menu. For example:
Whenever you add or remove a tag parent pair to a tag repository, you will have to supply a reason (like when you petition a tag). A janitor will review this petition, and will approve or deny it. If it is approved, all users who synchronise with that tag repository will gain that parent pair. If it is denied, only you will see it.
+As you use the client, you will likely make several processing workflows to archive/delete your different sorts of imports. You don't always want to go through things randomly--you might want to do some big videos for a bit, or focus on a particular character. A common search page is something like [system:inbox, creator:blah, limit:256], which will show a sample of a creator in your inbox, so you can process just that creator. This is easy to set up and save in your favourite searches and quick to run, so you can load it up, do some archive/delete, and then dismiss it without too much hassle.
But what happens if you want to search for multiple creators? You might be tempted to make a large OR search predicate, like creator:aaa OR creator:bbb OR creator:ccc OR creator:ddd, of all your favourite creators so you can process them together as a 'premium' group. But if you want to add or remove a creator from that long OR, it can be cumbersome. And OR searches can just run slow sometimes. One answer is to use the new tag parents tools to apply a 'favourite' parent on all the artists and then search for that favourite.
Let's assume you want to search bunch of 'creator' tags on the PTR. What you will do is:
+Under tags->manage tag parents, on your 'my parent favourites' service, add:
+creator:aaa->favourite:aesthetic artcreator:bbb->favourite:aesthetic artcreator:ccc->favourite:aesthetic artcreator:ddd->favourite:aesthetic artWatch/wait a few seconds for the parents to apply across the PTR for those creator tags.
+[system:inbox, favourite:aesthetic art, limit:256]. This search will deliver results with any of the child 'creator' tags, just like a big OR search, and real fast!If you want to add or remove any creators to the 'aesthetic art' group, you can simply go back to tags->manage tag parents, and it will apply everywhere. You can create more umbrella/group tags if you like (and not just creators--think about clothing, or certain characters), and also use them in regular searches when you just want to browse some cool files.
