For me and many others, the first 8 or 16 bar loops are the best part of making music. I’d like to be able to extend the current loop when exporting my initial ideas, without having to manually set or mark it in the arrangement. Extending a section isn’t always straightforward, especially in later arrangements. And when I listen to an exported MP3 in the car or elsewhere, most players can’t loop it cleanly. There’s always a short click or pop. Either because the player can’t do it properly, or because delay effects, release, etc. at the end of the loop don’t match the beginning.
Therefore, the export menu should detect whether a loop is currently active, and if so, allow you to enter a loop factor x.
