I make use of the macOS/Linux package manager ‘Homebrew’ a fair amount. Whether that's looking up something in the docs, tracking down a formula or just checking out a new app.
By looking to save on jumping in and out of windows (no doubt, all of about 10 seconds!), a standard little sidebar for Opera Browser, forked from ‘Sidebar Extension Boilerplate’, cropped up on this nondescript corner of Github.
Made solely for convenience. Why not have a go at making one yourself?
