Hi,

I am all for the future with blocks in order to compete with Wix/Squarespace and be modern without bloated themes and plugins, BUT

the current stage of Gutenberg is extremely terrible, having some basic functionality not working.

See the videos

1) Drag 'n' drop produces extreme lag for images; https://www.youtube.com/watch?v=XhZs6jq8-MY

2) Drag 'n' drop doesn't scroll the page up and down; https://www.youtube.com/watch?v=659IOT5T79M

3) Drag 'n' drop doesn't permit mouse scrolling; https://www.youtube.com/watch?v=fbCmw9LDMnk

4) Movement symbols - hard to use and with issues; https://www.youtube.com/watch?v=WU2AxvzX1KE

5) Cut, Copy & Paste doesn't work for block images; https://www.youtube.com/watch?v=o904E_zd5YY
