Maybe I’m losing it…I have a memory of Codea from who knows how many years ago having a way to see a dropdown list of your file tabs and selecting one to go to it. Was that ever a thing? Did that go away? I have a new, large project I’m working on and it can be cumbersome to swipe across all the tabs to get to the tab I want.
@brianolive - another work around this could be to put all your well established routines into a separate or multi separate files and call them as dependencies, leaving the nitty gritty development file smaller and more accessible.
