Thank you for the suggestion.
Yes, notebooks and tags on the sidebar are sorted alphabetically.
This is intended behavior.
Prefixing notebooks and tags with emojis sounds a personal preference but interesting.
Perhaps, some people may use them to move some notebooks to the top.
Let me carefully consider if there are unexpected side-effects.
Ignoring emojis in notes is hard as it requires changing the indices.
hah, I use them a lot for tags, I think it messes with it as well. Actually many apps handle this by letting you assign a separate emoji for each item, like MS To Do. Not suggesting you should do that @craftzdog, but it may be more common than you think.
