It’s tempting to think that adding a feature like this is just about adding the functionality — but there’s a bunch more to it than that.
Here you see the gory, deliberate details that a responsible developer must consider when adding even what seems like an incredibly “easy feature.”
Without a doubt, the part of my job that slows me down the most is exactly this kind of consideration. I want to add a new feature, but not until I have evaluated how the feature best fits in the structure of the application as it exists today.
Sometimes even an “easy feature” requires massive overhaul of the application, so that it doesn’t feel tacked-on or cheaply done. If the feature is important enough, it’s worth practically rewriting your application, just to add something that looks like it must have taken all of 10 minutes to do.
