Would be nice to have a General/Custom Board View where I can select the column and row data + I can define the content of the cards / table cells.

Maybe, also sub-column and sub-row category (as pivot works in Excel and Google Sheet).

///for the PO/devs : this way you solved (almost) all requests about this-and-that-kind-of-tables/boards/reports + there are only few PM tools that offer this flexibility///

Hi, I had the same idea, but I would like to add to expand on this to also use tags. This way you can also setup a board view like Asana or Meistertask where you want to use the columns more for categories than statusses.

You could use tags for this purpose :)
