My initial response was to the appearance of this is approach. Issues I've
discovered in subsequent use in no way have distracted from that initial
opinion. I found several things to report, but I'm getting different
behavior on Android where I have to use Firefox and Chromebook where Chrome
does not crash. My children have the Chromebook and Windows 10 machines so
I have to wait till they're not working to try experiments on either of
those.
The first issue isn't really in this app. All of the labs I remember using
begin with the sentence:
To advance the lab, select menu Help|Studio|Advance or the
corresponding shortcut.
To my knowledge, the Android version has never had that menu choice, but
it's always been so different than every other platform I've never reported
it. That seems important to overcome on something you'd like to show people
first. If I'm right about that sentence being in every lab, perhaps the
simplest thing to do would be just replace it with an empty string in this
app and assume people would use the advice at the top of the Labs menu.
I haven't tested Windows yet, but so far I cannot advance a lab with Crtl+>
anywhere.
Pressing enter after a result echos the last output, unless there was none
as happens with plot. In that case
Edit Run > Line
echos the line you typed as part of your entering the request initially, and
Echo Run > Line & Show
has
output_jrx_
under the plot.
As it is currently working, I don't know the point of having Line & Show
under Echo Run. I don't know what Connect and Disconnect under Server do. I
also don't know what Center Panes under View does.
My own preference for introductory interfaces is to provide as few choices
as necessary, and to choose both descriptive words and organizational
positioning to ensure the meaning of each is clear. To that end, several of
the items in the previous paragraph might best be removed. Furthermore, a
number of the options under Links seem better categorized as Help, and I
would argue for choosing one initial form of help even though I don't much
care which one it is.
