Hello, sorry for the triviality of my questions but what can be the reason why "Update Thumbnail and Snapshots" cannot actually update any of the Manipulate panels that I have in my demonstration ? Please find it attached.
My second question is how to deal with the fact that the length of control value increases, increasing the size of the Manipulate panel ? The explanation in the Wolfram guidelines are not too detailed.
Thank you very much, 
Best regards,
Nicolas Murer
