Wide theme for instagram. Uses a majority(60-70%) of the screen space for displaying pictures. Work in progress, struggles a little when width ~ 2*height.

InstaWide.css

@-moz-document domain("instagram.com") {
/*
 * For widening all thumbnails on the profile page.
 * - Count per row remains the same, 
 * - More screen space is utilized with this
 * - Also I dont want to click on shit to look at it clearly 
 *   (instagram pre-loads images upto 1080w, so this can be as good as you want it to be)
