what about modules of different widths

that already works, adapter will be as long as the longest 1u module

and more than 3 modules to make even sizing with a larger module?

I don't understand this

also is there any way to do this on a phone or tablet?

yes. If you do not see the rotate button you have to activate that in your usersettings in the planner menu options.

Is there a way to have say a 28hp 1u module in one row and then a 20hp 1u and 8hp 1u module combine for the next?
