If you have more desks than students, you can avoid awkward gaps by filling a chosen part of the classroom first.

If your classroom has extra desks, your seating chart might end up with akward gaps.

Choose which desks to fill & which to keep empty

To fix this, you need to decide which desks you want to be filled and which you want to keep empty.

Decide which desks you are going to fill and which you are going to keep empty.

Select the desks you want to keep empty.

Uncheck the "Allow students here" option for the selected desks.

Now when you shuffle your class, Shuffle Buddy will leave the disabled desks empty, filling the remaining desks with students.
