There are some issues that would be nice to improve/allow:

archive names with dots can be given to .fract files
However, for image files, the name is cut down to the first occurrence of a dot:
c2i0E-1+2(-0.71;.59,-.06)(-.73;.59,.07)1280x1440st003lunitas.fract
but the image with the same name only saves
c2i0E-1+2(-0.png

I am getting a large percentage of wrong estimates (46%) in some imaginary scator fractals.
For example with the .fract parameters attached. Is there an impact of these wrong estimates in the image?

Hi manuel

1) file names.   Zebastian, has just made a change for the next release. I will check and see if it addresses this issue.

2) I had trouble using analytic DE with the scator formula. From memory I think I used  logarithmic DeltaDE  for distance estimation.

Percentage of wrong estimates is  a good "guide", and  46% is usually real bad,

Later today when I have some free time, i will have  look at your settings file to see how bad the DE is.

1) latest change has not addressed this

2) the scator needs a different distance estimation calculation or brute force rendering.In respect to a  different DE calc. I do not know enough to make one. sad

I think Fragmentarium may have a brute force rendering option, but I have never used it.
