I have some suggestions for features in the software, I have only used the Windows software so not sure if similar in the tablet applications.
It would be useful to be able to export data from one screen frame into a comma separated file (.csv) so could be used with microsoft excel, and also export data for longer time periods for data logging (eg. up to 24 hours at 10 minute intervals).
It would be useful also to allow screen capture (.bmp or .jpg) direct from the software.
For the voltage range and timebase change, a drop down list would be preferable as it is quite slow to change with the up/down buttons.
