Feature - Ability to edit list of hidden items

[Codain]

Using Sozi 18.04, I suddenly discovered that one of my SVG item was hidden and discovered it was part of the elementsToHide list in the JSON. I do not use it for any Layer positioning (which is the only way where one can choose to hide the item).

The only way to fix this issue was to edit the JSON.

I would like to have the ability to visualize and edit (at least: remove) the list of such items directly on the UI whithout having to go through each layer to see if one uses it (which xas not the case in my example).
