A lot of people seem to like overview maps in their editor. I've heard of people refusing to leave SublimeText for just such a reason. So in an attempt to reduce friction even further, I spent a few hours making a minimap for Builder.
I was initially quite worried that this feature would impact the editors interactivity. But being a little bit careful seemed to work out well.
It needs some followup work for things like a11y (including focusability). If this is interesting to you and you have suggestions on how it should work, please contact me however you like.
You can click directly in the map to jump to that location. Additionally, you can grab the scrubber and drag.
