Diddo!!! It would be nice to have a check box next to each question, where you could select the ones you want to use, and then add them to the que all at once.

Absolutelly! That would be great! It is very time consuming doing it one by one.
Hi,
I think it will be very useful to have the possibility of selecting a group of questions by checking the selected ones (a checking box for each question will be need) to add them altogether to a Question Queue (I find it time consuming to have to add each question. In this situation, it will be also very useful to have the chance of “Selecting all” the questions in a folder and/or have the possibility of adding the whole folder to a Question Queue in a row.
That will be specially useful when you want to use some questions or a whole folder a second time (with the same classroom a week later to see improvements, with a different classroom of the same level, next year with a different classroom, …).
I think that would be great!
In fact, I think Plickers is already great, so it wil be greater!

Definitely a time-saver; to be able to select more than one Q at a time from a folder within the app for queuing these.
