You will need an extension for what you're trying to achieve, as it's counter to the intended functionality of Roll20. Something like this , you might have to search around a bit and experiment. I have no personal experience with any extensions like this, it might melt your PC or it might do what you want. I don't think you'll find much help with this, as you're disabling a bunch of functionality and can't even see the canvas when viewing a character sheet - I doubt it's a popular workspace option. As Farling pointed out above, double-clicking a character sheet will minimise it and is the preferred option for single monitor setups, as you can still use drag & drop and see the canvas, and the chat bar.
