[FEATURE] - Allow to put only one bookmark per file, and replace the position when re toggle

[TheElegantCoding]

Allow the option of just putting one bookmark per file whenever you want, this will save only the file to the bookmark and you can navigate only to the file you save easily.

When you re-toggle the file, the position of the bookmark change to the new one, it doesn't generate two bookmarks per file.

This is only for the purpose of navigating fast, it would be nice a command to delete the bookmark from the list no matter what position you are

Maybe not all people want this action so it has to be in the settings of the plugin to allow that
