Works great with twentytwenty theme

Great blocks that I use everyday with WordPress 5.7 and the defauly twentytwenty theme. Keep up the good work!
The ?Content Timeline“ gets really very, very slow if you edit it with many items (at the moment I have a timeline with 170 entries, just plain text) and I nearly can’t edit it anymore because it is so unbelievable slow.
But otherwise I really just love it. Maybe you could add a remark to the timeline block, that it is just suitable for *some* items?
