Version 2.7.0 -13 November 2014 New Feature: "Easy-Add Tags to Purge" to the Tag Rules Table; Revised User Instructions.
The new "Easy-Add Tags to Purge" to the Tag Rules Table functionality closes the circle with the previously released Tag Rules Table with User Maintained regular expressions and simple matches to either change or delete Work Tags during Tag Scrubbing at both the Book Level and the standalone Tag Scrubber Job for all books.
This new functionality finds all "real" Tags that do NOT have a rule in the Tag Rules table (nor are used as a NewTag when changing and Old Tag to a New Tag), and loads them into a typical Calibre-style list editor. Instead of editing them (that is not what this is for), you simply select with your mouse the Tag or Tags that you want to forever vanish from the current and any future books in the Q&S library. The new functionality creates a regular expression rule (so upper or lower or mixed cases do not matter) for the selected Tags, and adds that rule along with a PurgeTag indicator of True. Just select, click the single icon, and click "okay" to exit the dialog. Easy as pie.
No more excuses for (tens of) thousands of useless, meaningless and even annoying Tags.
Of course you can still maintain the Tag Rules table by hand via the end-user friendly (and free)
sqlitebrowser.org tool discussed in the Q&S User Instructions. That would still be needed to change Tags to another Tag (e.g. the regular expression that changes the myriad forms of "Science Fiction" to a single Tag value, such as Fiction:Science or Science Fiction or whatever you wish for your personal Library; it is your Tag Rules Table...).
