BIG yes, with reasoning elaborated for others to discuss:
- Coliseum/Gathering tabs
This provides a quick means of seeing where one might want to grind or gather for the day, and I always found these tabs super useful (definitely not biased as the creature of the gathering tab or anything ;p). This feature isn't implemented into the revamp in any way.
- Holiday/Retired tab
Holiday and retired familiars are an end-game goal for many users, and this tab serves as a sort of checklist of goals. That being said, the bond status can likely be removed.
- Baldwin/Swipp tabs
Another feature not included in the revamp in any comparable way. This serves as both a progress checklist and a means of seeing which familiars you have yet to make a (likely expensive) trade/brew for, so that you don't double-do.
- Main tab (with revamp)
Most of the main tab is included in the revamp, and that being said, as it is now, it can likely leave. However, I'd like to make an argument for a repurposing of the unincluded features of it; primarily, this would be the acquiring locations. Perhaps this can be retooled into something more resembling the Coliseum and Gathering tabs, such as Marketplace and Seasonal tabs.
Overall, this sheet covers a number of functions that aren't encompassed by the revamp. However, the revamp does leave it more free to "clean house", and remove some of the functions that users of the sheet (and the author!) may find more tedious to upkeep, such as the bond status and current possession locations.
I've been involved in this sheet for a long time, so I'd be sad to see it go, but if you still see a purpose in keeping it alive, I'm here to stay
