Hi Dennis,

Much thanks for the feedback!

1. Thank you!

2. Thank you for the very nice comparison image. We'll work on this.

3. This is an underlying ImageJ function, but we'll consider if we should try to change it. "regex" means regular expression, which is a powerful syntax for filtering text (i.e. filenames in this case). You can search for that terminology if you are interested to read more about the capability, but generally this can be left blank if you want to load all files in the selected folder, or simply include a part of a filename that matches all the files you want to load.

4. We'll add help text for the items with missing entries. For now, I'll say that Smoothing Filter Radius is the radius used to Gaussian smooth the image before searching for peaks. If too many peaks are being found, then the filter radius should be increased. Generally, 3.5 pixels works fine for most image sequences I have tried. To be clear, the smoothing and peak finding happens on an image copy that is not displayed, and most importantly doesn't affect the version of the image that is used for photometry.

5. Ignore the debug option. It is there for our development use. We'll eventually remove it, and hope to add more algorithms for optimizing comp stars and detrend parameters in those drop down boxes in future AIJ versions.
