Below is my best attempt to put everything I've been working to compile into a list for the past week or so. Tried to keep it brief and constructive. My philosophy centers around the efficiency and ease of which I can work with many posts and their sets. I spend many hours, which is likely not wise, on managing my sets. Unfortunately the redesign has crippled me in that area in a few ways. I'll be following this post closely and I'm willing to work with people to see things improve. I'm also curious who else shares these opinions.
Anyway, here's the list of every bug and grievance I have with the redesign:
* Adding-To-Set notifications need to be always accurate; I have had a few times where I've realized that it said it added it to the set, but it did not. It is rare, but has happened a few times. To fix this, I believe the notifications should be changed to be more verbose and accurate. For example, the order should be: Attempt to add to set > If failed, give error and reason > Otherwise, verify that post is now in the set > If true, then display "Added to set". Also It'd be nice if it had some kind of short-term log instead of only being able to show one message at a time at the top. If all of this could be realized then that'd be amazing.
* Sometimes when adding to a set, I get "error: " (blank) and it cant add to the set. This seems to only be on e621.net/post pages WHILE the URL contains previous search information. Happens fairly often to me, but not always.
* The 'add to set' button when viewing a post places the set selector in the middle of the screen which is very inconvenient, personally.
* I'd love a hotkey for adding to the currently selected set or the last-added-to set.
* Larger thumbnails when searching would be nice, but I can understand this not happening. It's a low importance nit-pick.
* I'm unable to edit or work with any set which is full/over 10k posts.
(Edit:)
* Also, sets are no longer listed in alphabetical order when adding to a set.
