On an individual tree level, yes. But planting trees usually implies either: - Designating new areas for entire forests to be grown (which all together is a store of CO2, even if individuals die and rot) - Many individual trees in towns/cities, which would presumably be replanted if they die and so, again, in summation are a store of CO2.

Or just encourage everyone to have oak panelling, wood floors, and a huge excess of fine wooden furniture

I like the idea, although really this is very similar to Chrome (and other browsers) where you just never open the settings tab. Except for the search bar, this is just one of today's browsers with tweaked defaults.

I really don't see the disadvantage, minus the small developer overhead, of having all the choices they have made here configurable.

I wonder.. is it built on Chrome under the hood?

Anecdotally fits in with my experience. I always sat at the back off the lecture theatre (but its only 20 rows deep), and the people with laptops were almost always doing something other than paying full attention to the lecturer. I used to leave my phone in my dorm lest I end up checking out a tech blog and be completely lost of the rest of the lecture

I created a logic circuit simulator called GatePlay - aimed for casual use by beginners/students, but the simulation is not over simplified.

I know of a couple of small bugs already, but feedback would be awesome!
