I really like the new look and features of Stacks 3. I upgraded as soon as it was available.
The only thing I can see that could maybe be incorporated in a future update is the way it handles showing the stacks by Author.
I like to look at my stacks by Author, but I don’t like to see every stack by every author. Its a pain to scroll through all stacks by all authors to find one I want by just one specific author.
What would be nice is if the authors could be closed up like in Stacks 2. Then when you get to the author you want, click on it to open and see their stacks and then close it again when done.
The other thing is that some stacks are listed with the Author, they are just general or miscellaneous. But I know that is not a Stacks 3 issue, that is an issue with the Author not giving the correct setup/info.
