Viewers can't see if a component is fixed position or not

hi. i have an issue and a suggestion. I’m a designer (editor) and work with developers. (viewer)

issue 1.
I set a navigation bar as a fixed position when scrolling. but there’s no way for viewer mode developers to check if it’s fixed or not when scrolling.

suggestion 1.
the reason why I invited developers as viewer is b/c to prevent the design components. they can delete or move the components by accident.
the problem is, since they are viewers, they can’t use a ‘find’ plug-in. they need to find specific frames or components quite often when working.
i hope you open the access to install plug-ins for the viewers as well.
