Idea: Adding pictures to the User Guide Walk-Throughs

[TomDonoghue]

As a possible suggestion, one thing that might be useful in the user guide, specifically in the guided walkthroughs for ECG and RESP data, would be to add some pictures of "this is what the screen should look like right now". This should hopefully be relatively easy, since you use a standardized piece of data, and I think would help the new user, especially right at the beginning (at moments, for example, I wasn't sure if i had done things right / or if I could see the expected display).

Also, it might be useful to add a note of any steps in the process that make take some time to process. Not sure if this is expected, but it seemed to take a while, when I was running things to, preview a segment, before it could be confirmed. If this is expected, I would just not in the tutorial "this step might take a few seconds", etc.
