I am finding after the first week with Affinity Photo that it really does not like a folder-based workflow with sources and Affinity files in the same folder. Every time I do a "Save As" or an "Export..." operation, it assumes I want to save the new file in the same folder I saved the last one, not where I imported or opened my source materials today. My workflow keeps all files shot by date together, or all files related to a certain client together. If I am not very careful, I end up saving new work into a completely unrelated old project area from a different date or client.
Please support a preference to work with sources and projects and results in the same folder by default, not folders used in past editing sessions.
