Speaking as someone who does their development in Vim (with YouCompleteMe / NerdTree / CTags installed), that's pretty much exactly what it looks like when I'm coding to this day. OP recognises elegance when they see it.
A designer knows he has achieved perfection not when there is nothing left to add, but when there is nothing left to take away.

They are remarkably expensive, but 'microchip reading cat feeders' do exist, that only open for the pet with the correct chip in their back. There's a token for their collars if they're not chipped, too. Made mealtime with our three much less fraught - we'd have ended up with one spherical cat and two rake-thin ones, otherwise. Also make medical treatments easier - you know who's the only one who could have eaten it.
