@
DawnDawn88 - my suggestion is to watch the
Video Tutorials
As a general rule I don't like or recommend 'instructional' videos, but these are an exception, I watched the main one in segments - pausing at the end of each to try to use the feature just described - rewind/repeat if I didn't get it.
I also recommend skimming the
calibre User Manual introductory page and Table of Contents, and the "Graphical User Interface" section. That will introduce you to the 'calibre terminology'.
I couldn't see anything in your first post that you can't do readily in calibre - once you get to know the basics.
