This would be huge, it is one of the biggest struggles for teachers learning Toddle is that they just aren't sure how everything will look for students and what options students have for submissions.

We get around this now by having some test students that I offer to put in any teachers class who wants one, but this is clunky. The teacher needs to assign the task to the test student, log in as them (often in an incognito window or in the student app if they have an iPad), view the task, and then go back to the assignment to make changes if they noticed anything they wanted to add.

In 1.0, at this point once you've assigned something its a copy of what is in the planner so then teachers need to update the assignment and then go update the planner version. I think this will be better in 2.0 with the copies, but a preview of the student view would be so helpful with fewer clicks.
