> I have a screen with a large number of blocks. The blocks execute fine on my device so everything is working great, but the Thunkable block editor on my PC is very laggy. Anytime I move or modify a block, there is a delay before I am able to move or modify the next block.

I have got the same problem with lagging and i have 4300 blocks in one screen

is there any solution to stop the editor from lagging its a pain to edit the blocks on the screen due to the lag??
