As another anecdote, I made a couple of Chrome extensions years ago to improve my development workflow: - One would switch to an existing tab with the same URL, instead of opening a duplicate. This made it easier to click URLs in error/debug messages without making the browser unmanageable (IIRC this was just a copy/paste of someone else's extension, which didn't work without me fiddling it) - One would add keybindings to the output of Drupal integration tests. These tests would say things like 'visit X', 'click the Y button', 'enter Z in the form', etc. and would save each page, so if a test failed each step could be viewed in a browser. The only problem was this is tedious, so I made an extension which bound the left/right cursor keys to stepping through these pages. Made it much easier to skip through the setup and get to the bug (e.g. adding items to cart, when the problem is in checkout).
