Btw, in the meantime, I managed to create a preset manager based on single files : presetmanager2.zip (1.4 KB)
Just uncrompress everything and load the .csd file.
You can save a preset using the save button anywhere you want
If you save a preset in the "presets" folder in will appears in the listbox after the next plugin startup.
To open a preset you have 2 ways : the open button to search for any files on your computer, and the listbox to quickly load a preset saved in the "presets" folder
you can reload the lastest preset using the "reload" button.
For some reason, the preset name doesn't displays properly when you use the open button (maybe because open load the path with "/" and the listbox load path with "\"
Maybe it will be useful for someone
