I have just started playing with logseq and noticed infinite canvas. From my experience with large DOM is that at some point things start to lag, long before Figma would (my understanding is they have a custom GPU engine).

I have for long time hoped an API for capturing DOM elements into an image would come, but it is not the case. It needs enough interest generated to be pushed as a proposal.

I hope admins do not mind me posting this here. I am trying to generate interest for the idea screen-share/element-capture#5 (comment)
