In the current process as far as I can see, when uploading a brand new image entry into the CMS the plugin automatically generates thumbnails of all active profiles.
It would be good if that feature could be optionally turned off (in the setup section).
In my website builds there are various profile sizes for different areas/content of the site, so not all active profiles are relevant to a specific image (and making profiles inactive removes the option to create that profile size via the dropdown list in image edit).
Currently I have to delete all, then recreate the ones I need. I know I could leave all the other auto generated ones and simply not use them but it adds cruft to the panels and filesystem.
