Lowercase all tags:
*
Set all tags to lowercase for consistency
*
Recount tag use:
*
If the counts of images per tag get messed up somehow, this will reset them
*
Purge unused tags:
*
Get rid of all the tags that don't have any images associated with
* them (normally they were created as typos or spam); this is mostly for
* neatness, the performance gain is tiny...
*
Convert to InnoDB:
*
Convert your database tables to InnoDB, thus allowing shimmie to
* take advantage of useful InnoDB-only features (this should be done
* automatically, this button only exists as a backup). This only applies
* to MySQL -- all other databases come with useful features enabled
* as standard.
*
Database dump:
*
Download the contents of the database in plain text format, useful
* for backups.
