I often use different combinations of the same paradigms in my research, but copy-pasting routines and rebuilding loops every time is a nuisance. So I wrote a little applet to facilitate merging experiments. It allows me to upload multiple .psyexp files and checks if there is any overlap in the component and routine names. If not, it lets me sort the experiments in the intended order and download the merged result. I thought it may also be useful for other people, so I uploaded it here: https://adjus.shinyapps.io/PsychoPyMerger/. Feel free to use it and give feedback.
