You could have a look at the GeanyNumberedBookmarks plugin which has feature close to what you request, it can save fold states and bookmarks for documents and restores them when the document is opened again. Currently, it does not yet support restoring line number and column but it is probably easiest to implement in this plugin as there is already the infrastructure for saving settings per document and your feature is close to bookmarks.
I just transferred this issue to the Geany-Plugins project where the GeanyNumberedBookmarks plugin lives. -- You are receiving this because you are subscribed to this thread. Reply to this email directly or view it on GitHub: https://github.com/geany/geany-plugins/issues/838#issuecomment-477953881
