about "private" photos

Hi to all

About the "private photos" problem...
For example:
a picture of you making strange faces, or walking without trousers at home, images that you don't want to show to your aunt when you show her your collection.
a picture of your neighbor shoveling snow and throwing it to another garden, that you don't want to accidentally display when you are showing pictures to someone else (maybe the neighbor himself).

I was thinking that an easy way should be to add a specific tag ("private", or "family"...) to these pictures, and apply a set of filters to hide them.

Is there any way to make custom buttons and add them to the bars?
It would be very helpful (instead of searching the filters section, find the tags, select them for hiding and apply) to customize a button (a panic button :-) ) in the toolbar to apply immediately a set of memorized filters.
Buttons that should be very helpful for other type of filetring too.
I know almost nothing about programming, but I think this thing may be easy to implement. Or not?

Thanks
