With ver 10.80, the collapsible section feature has been added, including images, etc., which is nice.
So I thought,
(1) It would be useful if it is possible to prevent collapsible sections from being expanded with a password, similar to "Encryption of selected strings".
It is not encryption, but only makes it impossible to expand, so the string can be searched.
(2) Like the checklist, it would be essential to add a handle to the left end of the heading that can be grabbed so that it can be moved up and down to rearrange the order.
I would like to be able to grab the handle, copy the entire heading (including contents), and paste it into another notebook.
Currently, you have to expand the heading and then select the whole thing, including the heading, to copy it. This is annoying.
(3) It would be nice to have a menu of all collapsible sections expand/collapse.
Because it's troublesome to expand/collapse them one by one.
