Blueprint Browser shows blueprints with non-public skills

[doomlord289]

While searching the blueprint browser to see if there were any obscure items my industry alt could not yet build, I noticed when I set the "Filter" dropdown to "Blueprints I cannot use" and the "for" dropdown to "Any Activity", there were still a lot of blueprints listed. When I looked at them, most only required skills that are marked as non-public, such as Hypernet Science, Factory Management, etc.

Would it be possible to add a checkbox like the one at the bottom of the Skill Browser that reads something like "Show Blueprints Requiring Non-Public Skills" to filter out the blueprints that require skills that aren't available?
