Sorry it seemed like I don't want to help someone - I was trying to add to the GP's thing about how he/she does not enjoy co working spaces because of broken concentration by others asking to watch their stuff.
Of course I would help keep an eye out, but I would also like to help that person with other security / safety measure too, so they would be more secure in the future -
I think some people need a little auto-flag / light that pops up saying "I'm in the zone, don't break my flow" - I can relate to working on a thing and several side issues pop up that remain in short-term attention memory while changing code.. and getting through the mental checklist - and then get interrupted by family.. and try to come back and spend an extra 20-30 minutes trying to remember..
I could of closed my door, and should have - so it's not their fault.. so I see both sides of it. Generally speaking I would prefer to be social and helpful and can get my groove / flow back anyhow - so certainly being available to be present with other humans is often a higher priority. I also understand some others may have deadlines or whatever.
Also - what happens if someone else distracts you and you don't keep an eye on the laptop and something happens to it. Or what happens if two guys in black suits with sunglasses pop in and swap the laptop and look at you and give you the shh and finger gun to the head. I mean, what a predicament to be in.
I know none of that will ever happen, but someone's competition, an ex lover - I mean any sorts of things - many laptops are just value of the hardware sure, but some are data on the device and that could be a lot of responsibility -
I'm just sayin' - if it's not a chromebook, lets get some more layers of security! and an odd "all seeing eye" could not only be semi-cool tech, but a conversation starter if that's part of the appeal of engaging in the 'hey I'm running to the toilet' starter :)
Now, how to make an auto-do-not-disturb- I'm-in-the-zone, not-on-facebook bluetooth light/sign that detects typing in visual-studio/sublime/notepad++/jetbrains vs scrolling some web page. Might need to be more than a red/green light busy/not-to-busy; maybe do-not-bother (writing code)/available-to-chat(reading-perhaps)/please-save-me (I've been on reddit/fbook more than 30 minutes).
