I face a scenario that might sound familiar to people with toddlers.
If you have a toddler near your family laptop you might want to have the ability to temporarily disable the majority of inputs (mouse/keyboard) while keeping the desktop unlocked. We could name this option “Baby Proofing”.
That is useful in cases where you have a kids’ movie playing on Youtube. If the toddler (due to excitement/curiosity) starts pressing multiple keys (especially on a laptop) then it messes everything up. Confusion and crying ensues.
I propose creating an option to give users the ability to create a custom shortcut that disables the mouse and ignores all keystrokes (apart from the unlocking shortcut).
Once the user gives the correct key combination then all the inputs get restored.
Happy to hear your thoughts!
Edit: Now that I thought more about it this option could be useful for cat proofing as well!
I don’t have children, but I take care of an older person who’s hands shake a lot, and because of this has inadvertently messed up settings leaving me to fix things. I would love something like this but just for say settings, icons, and panels and still be able to allow them fairly easy access to their email and browser.
