Add "Grid Calculator PRO" by default in Adobe Indesign CC 2020 or improve the setup of grid / baseline grid
The plugin "Grid Calculator PRO" (https://www.designersbookshop.com/grid-calculator-pro-edition.html) is perfect.
With this plugin you can configure the grid and/or the baseline grid precisely much more that with default setup of Adobe Indesign CC 2020.
It would be interesting to integrate this plugin directly in Adobe Indesign CC 2020 or modify the currently setup of the configuration of grid / baseline grid feature adding more options for this elements.
