Tutorial Feedback

This issue will collect all feedback submitted via the feedback form at the end of each tutorial

----

Results have been [aggregated](https://nbviewer.jupyter.org/github/bebatut/galaxy-training-material-stats/blob/master/src/analyze_feedback.ipynb) and [pro/cons per tutorial](https://github.com/bebatut/galaxy-training-material-stats/tree/master/results)

Review the feedback aggregation notebook linked in the issue and the per-tutorial results directory to understand the collected concerns. The issue does not identify a specific tutorial or change, so work is not ready to begin until an actionable scope and completion criteria are defined.
