Last used "Markup type", "Initial window state", "Style", "Color" & "Author" remembarable !

 * Xreader version (2.4.2)
 * Distribution - (Fedora 30)

Issue
All these mentioned annotation properties should be rememberable, so that user have no need to reset them every time she/he adding new annotation.
Currently they are sticky on yellow colour with highlight type & 100% opaque, close window state, & PC name as an Author name.
You can make all these a default, but you should make any change done by user rememberable so that she/he need not to reset them every time adding new annotation.

Steps to reproduce
Try to add an annotation, then change it's properties (like use "underline" or "red colour") then apply new properties of it. After that add new annotation. You will see new annotation return yellow colour highlight ! This is very annoying !

Expected behaviour
Last used annotation properties (ALL OF THEM) should be rememberable not merely during same session, but also after closing program & relaunching it again.

Other information
Again I insist that setting should be rememberable even after exit the xreader & relaunching it again.

Start by tracing how Xreader creates annotations and stores their markup type, window state, style, color, and author properties. Check the existing persistence mechanism and annotation-related tests, if present. Done means each changed property is reused for new annotations after closing and relaunching Xreader.
