Hi Marek - the next release of the plugin lists the number of surfaces that get cached. Perhaps when I am opening your pla file it is adding to my existing library - so perhaps you do not have 600 surfaces - only me! It is taking about 1 min for the plugin to open for me - if you are not getting that delay - you may not have an issue. I just raised the issue in case if you an issue for you too.So where is the list of 600 Surfaces to be reduced, please?
