To answer your question, if you click on the column headers, it will sort by those columns, but you can set the default sort in Preferences ==> Tweaks
e.g. I use
Code:
#: Specify columns to sort the booklist by on startup
# ID: sort_columns_at_startup
# Provide a set of columns to be sorted on when calibre starts
# The argument is None if saved sort history is to be used
# otherwise it is a list of column,order pairs. Column is the
# lookup/search name, found using the tooltip for the column
# Order is 0 for ascending, 1 for descending
# For example, set it to [('authors',0),('title',0)] to sort by
# title within authors.
sort_columns_at_startup = [('authors', 0), ('series', 0), ('title', 0)]
You might just want to use
Code:
sort_columns_at_startup = [('authors', 0)]
You can plug your tablet into the computer and calibre will recognize it and allow you to "Send-to-Device".
