Back button in the annotation process

[mapto]

First of all, thank you for a very useful semantic annotation tool. We are using it both for research and teaching. It is very beneficial both due the introduction of a protocol, and the analysis it provides.

We have situations when an annotator would like to return to a previous annotation they have performed. So we would appreciate a back button in the annotation process.

This might be something that you have previously considered and decided not to introduce, but our students were asking for it, so I am bringing it up.
