The SubframeSelector is a valuable tool, but I'd love the ability to save off and re-load a session.
For me, measuring a couple hundred target frames takes hours. The ability to re-load the settings and measurements from a previous run would avoid the costly measurement step. I could then experiment with different weighting and approval expressions, copy the chosen frames into different output folders, and then process each set for comparison.
The measurements can currently be saved to csv, which might not be ideal for reloading.
