Much appreciated for your efforts.
I can tell you, the only thing I ever used dragon-manager for, which was often, was to see when towers and dragons uncapped in relation to the builder hut and den level, as well as when those 2 uncap. I never cared much about attack power or hp since it meant f-all with the release of gears and riders.
If you could find a way to simplify that, I think it would be a big win for the more practical users of your resource.
Thanks again for your efforts, I look forward to seeing how it turns out 
Edit: while I use and appreciate what Kate is doing, a web based resource is more practical than having 4 or 5 Google sheets to sort though. Particularly for phone users.
