Hi

My seestar library was becoming to big and taking to much time to manage manually so i created a small tool, SSLM, which allow the below (Readme file) and also posted some screenshot after.

Still experimental but worked well in a local copy of my seestar library. Very useful to clean up and prepare exports for Pixinsight or Siril

If some of you are interested, i have a github repo for it and can give you access.
