Hi, thanks for the feedback!
Can you describe what ways the user interface and image handling are slower? I’d love to see if there’s a way to fix that.
For pasting as plain text, I totally agree. There’s a discussion about that on the GitHub repo, with a few ideas for improving it. In the mean time, a couple options are:
* Use the control+shift+v
keyboard shortcut to paste as plain text (works in most apps, not just Gutenberg)
* Insert a Classic block, and then click the Paste as Text
button, then paste like normal.
