I have a version of Thunder compiled for desktop, and it’s surprisingly easy to change the number of columns for Tablet Mode. There’s probably other places too, but the line I changed (from ‘2’ to ‘4’) is here
I realise you might not want to compile your own version, but it suggests that the developers could add ‘number of columns for tablet mode’ option relatively easily.
