I know this has been requested before but hopefully you can consider.
It would really be great to be able to save a project with all files listed in the file browser as well as the working directory and settings for the specific project. I often work on many session including various calibration sets and various filters etc. It takes a lot of time and some concentration to make sure all is allocated to the right sessions/filters etc. Two weeks later there is a new version of APP (Thank you for the great work) or I discover a new setting etc and I would like to try it out on a previous set of data. The process of loading many hundreds of files correctly again to try the new setting or creating new or better calibration files etc is would be so much easier of there were projects that we could just load, change the settings and rerun the integration.
