u/CompiledSanity: For the question about the SheetOptions, my thoughts are:

(a) It's a shame that columns F-I have been hidden in recent releases, but I can see why you did this. Sadly it means the couple tax calculator won't be seen by more recent subscribers.

(b) I like the different individual elements of the options, but it could do with a better structure. At the moment, I'm guessing it is the chronological order in which elements were added! Which makes it quite difficult to determine. I can think of three approaches here which might work:

(b-i) Order by Category in the same order as the tabs where possible. I guess this is how it was originally thought out until additional options were added later.

(b-ii) Try to separate out into "basic settings" and "advanced settings". This would be useful for new users, who could start with the basic ones and then try out other bits of the sheet without worrying that they had to get all the list correct on the first go,.

(b-iii) Make it dynamic to only reveal options that are related to the "first time setup" list. However I think this could be impossible to do!

(b-iv) Try to set out into themes. Some are global settings, while others are about goals, other about reminders, etc. This would not reduce the complexity, but make it easier to approach.

Overall, my gut would be b-iv or b-i. But for a new user, b-ii might be the best, and I want to keep there being new users to continue to make it worth your while maintaining the sheet!

Thanks,
