Now that iPadOS 13 has mouse support, I thought it would be cool if the "shift+drag" method of connecting modules would work, so that using an iPad with a mouse and keyboard could have the same workflow as with the desktop versions of SunVox.
The mouse emulates touches, so if this could be implemented by supporting "hold down shift on keyboard while dragging finger from one module to another" as a way to connect modules, it would hopefully work no matter what version of iOS/iPadOS is in use.
